Relentless by Karen Lynch Book Summary

**Now optioned for TV

Sometimes, the demons you fight inside are real.

Sara Grey’s world shattered ten years ago when her father was brutally murdered. Now at seventeen, she is still haunted by memories of that day and driven by the need to understand why it happened. She lives a life full of secrets and her family and friends have no idea of the supernatural world she is immersed in or of Sara’s own very powerful gift.

In her quest for answers about her father’s death, Sara takes risks that expose her and her friends to danger and puts herself into the sights of a sadistic vampire. On the same fateful night she meets Nikolas, a warrior who turns Sara’s world upside down and is determined to protect her even if it’s the last thing she wants.

Sara’s life starts to spin out of control as she is hunted by an obsessed vampire, learns that her friends have secrets of their own and reels from the truth about her own ancestry. Sara has always been fiercely independent but in order to survive now she must open herself to others, to reveal her deepest secrets. And she must learn to trust the one person capable of breaking down the walls around her.

READ THIS BOOK NOW. That was the Beatles book I have ever read. There were twists and i UAD so many emotions. I love this book.

Excellent Read!. Easy and interesting book. I enjoyed it and will read more by this author.

Finally a great book.. If you’re looking for a fantasy novel with a unique story line, an independent female lead, and scenes that will make you laugh and cry, this is the book for you. I finished in just 3 days and I’m hooked.

YES YES YES. Best series i have read all year! Obsessed over it. Loved it! Will never regret buying all of them + companion novels.

Less than a day. I read this book within 24 hours. It was that good! I legitimately could not put it down. I’m so excited to read the rest of the series!

Wow!!. I absolutely loved this book!! The storyline was riveting and it had strong and distinct characters. The story wasn’t dragged down and kept me entertained. I stayed up all night to finish this book!!! Definitely recommend Relentless!!

A bit juvenile. The ending was simply the beginning… yes her fathers death was resolved but it was definitely NOT satisfying.

Loved. It’s a little slow at first but this turned into one of my top ten favorite book series!

Thriller. Such a good book. If your looking for a thriller this is definitely the perfect book for you!

I’ve been waiting!. I’m a huge fan of supernatural and am always looking for a good read! If you enjoyed the Mortal Instruments series you should consider this book. Relentless includes many elements of most supernatural characters. The plot was well thought out and I couldn’t put this book down. It has a strong female lead who takes no bull which is a rarity in literature. Especially where she doesn’t start out weak or find her strength through a male love connection. Can’t wait for book two!

If you’re wondering if you should read...DO IT. I am very picky with books and was skeptical of this one, but I fell in love. This one is a little slow to start, but made me laugh, cry and love all in reading it. The characters are amazing and lovable and the twists and turns made me read the first 3 books in literally 3 days. Love love love this book.

AMAZING. I fell in love so fast with this! Cant wait to read the rest of the series

Seriously, I couldn’t put it down.. Every chance I had I was reading these pages, because I needed to know what happened next! Trust me it doesn’t disappoint!

Relentless. This book is very interesting. I was impressed. It was long but interesting enough to seem short. The characters are well developed and believable. I would recommend this book.

So good. I won’t Lie at first the main character was kind of annoying but as the book progressed I ended up enjoying it. A very good read can’t wait to read the second one

Can’t put it down!. Let me tell ya something, I am not normally a “reader”. I recently decided to get into reading because I wanted a new healthy hobby. I knew I loved things along the lines of supernatural, romance and mystery, which is what I searched when I came across this book. This book gives you the “on the edge” feeling at the end of every chapter, and you can’t help but read more! I love it! It leaves you needing more!

Read all 7!. Loved the whole series!

Fun and engrossing!. I loved the book with the small exception of the authors unwarranted hatred of the oil industry.

Wow. It’s not often that I give five stars to a book of this genre, but this was so well written and the characters were so ‘real’, that any star less just would not do. I thoroughly enjoyed every plot twist and characters from all the fairy tales. If the writing had not been so good, this could have been one hokey read, but this authors magic with words made me a believer in every revelation, twist and turn. Gotta go get the second book right NOW. I don’t want to miss a minute.

Yes!!. It kept me up all night to finish this book. I really loved it !!

Love this book. It was a great book and I am super excited to read the next one❤️

Amazing!. This book has been one of the most entertaining YA fantasy novels I have read since Percy Jackson, it had a very unique way of storytelling.

Amazing!. This series is so great and kept me on the edge of my seat the entire time!

Amazing!. It’s just amazing! Now onto the next book!!

I read the entire series in a werk. It’s just what my title says. I read the entire series in (less than) a week. It is gorgeous and just my style. Loved it. Devoured it. Have read them all now!

Realism in a fantasy. This book was compelling for the plot and the character arcs, but it was so refreshing because the female protagonist was not love sick or completely illogical. This book did a great job capturing the mindset and priorities of a 17 y/o without infantilizing them. The overall plot was full of action, covered the emotional turmoil of difficult life circumstances, consequences, trauma, and tribulations, and was incredibly well written so that you never felt lost, but you also could not anticipate the plot. Can’t wait to binge read the rest!

Relentless. The book is full of excitement and I enjoy reading through each line. It is a fascinating story, will recommend

I LOVE!. I was completely wrapped up in this fun new world and I loved all of the quirky fun characters. At first I almost got City of Bones vibes but the story line quickly twisted and it became unique and fun in its own way! Definitely one of my favorites, and I love the series just as much!

Well written. Enjoyed every moment!!!!

Relentless 😍. Absolutely loved this book. It was hard to get into but once I started reading. I couldn’t put it down😍

Must read.. This book was amazing. Kept me focused Snd story was amazing leaving it open to want to know what else happens to her. I loved it. Must read.

Just wow. This was the best book I have read. The action kept me pulled in the whole story. I absolutely loved the characters and their chemistry. This is a book about friendship and overcoming.

Buy it buy it buy it. Funny characters, interesting and surprising twists, and original story. I have reread this series 5 times and it’s still one of my favorites.

Love. I read the entire series and would definitely recommend.

Really great. Unique concept, well developed characters and great plot. It was very hard to put down. Anxiously awaiting the next installment

Such a great book!. Hands down one of the best books I have read in a while! A very original take on the supernatural plot line. There is so much that goes on in this book that I couldn’t even begin to give a summary, but the main characters are a kick-a** heroine and a bada** hero. What more do you need to know? Very high hopes for the series!

Relentless. This held me at every page. Very well written such that I easily pictured the characters in my mind. I couldn’t put it down.

Eh 2.5. Giving this a 2.5 stars. What I wouldn’t give to have a strong female and male character to just go out and say what they are feeling. Don’t get me wrong, I LOVE me some slow burn relationships but o m g. This story BARELY hinted even a lil romance between them and I kept waiting and waiting and waiting for some romance to be in this book...and there wasn’t. I’m not sure if I’m gonna finish the series.

❤️❤️❤️. OMG loved this book from start to finish. Couldn’t get enough of it. Read it all day until I was done. Can’t wait to read more.

This book should be made into a movie!. I loved this book series! ❤️ I have read them all more then once😂 And when I started reading I couldn’t put it down.

AMAZING. This trilogy quickly jumped to the top of my favorites. It’s so good! I love the twists and turns, the action, the drama, the characters, everything. I’m sad the story ended. I wish there were 10 more books. You can tell how much planning went into the plot. The author did an amazing job of connecting everything, nothing felt careless or aimless. It was all building to the climax. I’ve read so many books and have thought, “Why put that in the story? It’s unimportant.” Not once did I feel that way with these books. It all came together in a neat and tidy package that left me intrigued. I would recommend this to anyone!

Okay. This book certainly had it’s good parts, but at least in my opinion, it wasn’t amazing.

Relentless. I love this book sooooooo much!!!!! I’m gonna purchase the second series!!!!! So excited!

Relentless. Once I started to read this. Just couldn’t put it down. I must say it’s not really something I would normally read. The more I read it the more I wanted to read to see how it ends. It does keep you guessing.

A GREAT BOOK!. This book was a crazy ride! I was hooked right away and I can’t wait to read the rest of the series!

Loved it!!!. I loved this book sooo much!! I found myself thrown into the plot with all the characters, and it was like a separate awesome world away from my hectic life right now. Would definitely recommend this book! I found my self having to read it whenever I could. Definitely going to read the whole series!! I first posted this comment after I read the first book, and I am now on the fourth. The next three books are even better than the first one!! I have read through the comments and noticed that the people who don’t really like this book are upset that there is no romance between Sara and Nikolas. I’m not going to spoil the other books but I will say that in the second book and beyond is where the romance is. Definitely recommend the series!!!!!

Great book.. Well written and intriguing. It kept my attention. Just right on the hint of romance but still keeping it clean. The author portrayed both the characters and relationships in an interesting and engaging manner.

Incredible. I’ve read this series twice now, and cannot get enough of it. Definitely worth the read.

Life Changing!. This series had me hooked from this first book! Love the characters and the storyline never has any dull moments.

So addicting!. This was such a good book! Seriously, could not put it down. The story line sucked me in from the get go, and I’m loving the slow burn romance between some of the characters! The ending is satisfying, but also leaves room for the sequel. Can’t wait to read the next one!!!

Wow!!!!. Honestly beautiful ,it kept me reading ..wanting to find out more It kept me intrigued I loved it I wish the other book was free too 😭

Excellent. Wow, this is a fantasy I just didn't want to put down. From a author I hadn't heard of before. Needless to say, she is added to my must read read list. This is a very good fantasy, full of things I like and more. Highly recommended.

Amazing. Relentless will always be one of my favourite books. Every character was unique and perfect, Sara was so wilful and independent. The rest of the series were just as good, can't wait for the fourth one 😊

Amazing. This book is just truly amazing, I could not stop reading and so I spent my whole day reading. Not once did I get bored! Just truly amazing!!!

bloody epic. great book, finished reading absolutely fantastic, this is my favourite so far, I cannot describe how much I loved this book. this is my all time favourite book, I don’t think anything will be better than this book. absolutely brilliant.

Thank-you!. What a brilliant book, so much going on but not enough so you get confused. Definitely a MUST READ! Already read number 2 & anxiously waiting for number 3!!!! 😘😘

Awesome. I love these books and characters. Completely hooked... Have read book #2 and pre ordered #3... Can't wait!!!

An inventive fantasy. This novel blends fantasy and fairytale characters with ease. The female lead is complex enough to cope with the situations that she creates, as well as those in which she is unwittingly involved. The other actors bring their own strengths and weaknesses to the story. It’s a good beginning to a saga.

Absolutely hooked. Reading the free story in 'gods and mortals' I was hooked from start to finish, everything a human could need on the supernatural , it's fun, gory, fast, compassionate, full of my fave beings , easy to visualise everything and I even tear'd up a little at one point with a certain healing (ahem something in my eye here) ... yes on book 2 , very enjoyable and would love to see On Netflix 😈😈😈..

Amazing. Such a good story and book. Could not put it down. I read all three in the series within a week!

Relentless. Couldn't put the book down it was a slow start but well worth the twist at the end

Great read!. I couldn’t put this book down. I loved the characters so much. I’ve gone on to read all the rest and they are all just as great! Can’t wait for the next one to be released.

brilliant. Excellent read, I couldn't put it down and lost a nights sleep but it was worth it. Just starting book two.

Relentless. Action packed!

Really great read. Could not put this book down this Christmas week, it was the best thing I read in a long while. Thank you for writing this series.

A* Book. Excellent read. Love all the characters xxx

Really good. I had my doubts when I started but the more I read, I couldn't put it down. Finished it in a day. Onto the next...

A great read!!!. At first I purchased the book because it was free and I was out of reading material but I then read the preview of it and it sounded really good! Once I had started the book I knew I couldn't put it down until I had finished it so I finished it and now it is one of my favourite books. I even brought the second one because it was so good and am waiting for the final instalment of the series!

AMAZING😍. I've now read all of the books in this series and each one has been exceptional! I've never read anything as good and I just want to read more! I love the way that you feel like you are part of the story and everything is so well thought out it takes a minute to remember it's not true!

Relentless. This was such an amazing book. So much drama and was so gripping I couldn’t put it down. I highly recommend it for anyone who enjoys reading supernatural books, like me.

Amazing. Loved every bit.

Wow. I am not the biggest reader but I couldn't put this book down. A great read. The characters and the world created by this author are so full of life.

Relentless by Karen lynch. Amazing story, lots of great characters can't wait to start on the next book.

Amazing. I couldn't put this down and I was thrilled to see it was part of a series. Read all of them, real page turners with a great mixture of action and a hint of romance.

So fun to read !!!!!. I was a bit skeptical to read this book at first but once I started I couldn't put the book down. REALLY GOOD. I'm actually going to purchase the next one !

Very very good read. Started reading this as a lunchtime book, was late back from my lunch break everyday! It is such an exciting read! Can't wait to read the rest

Great story. Loved this story so much. Looking forward to the next 2. Thank you author xx

AMAZINGGGG. I enjoyed this book!! The characters were great! The storey line was amazing!!! I couldn't put the book down! Can't wait for the next one :)

Excellently written.. Delightfully convoluted

Good read. This book developed the story at a good pace. It definitely is the type of book that you want to finish and keeps you asking for more or what's gonna happen next? It's a little cliche for a young adult book but does have its own unique quality and spin to it at the same time. I'm looking forward to seeing the chemistry explored between some of the characters in the next book and some exciting questions answered.

Soooooo good!. I truly enjoyed the first 2 books and waiting anxiously for the last one. The story was interesting, never a dull moment and I couldn't put it down. Well down Karen Lynch, definitely keeping you in my favourite list!!!

Good Read. I enjoyed reading this story.

Review. Absolutely loved this book. It had great characters and was just so different and much more diverse in comparison to other books of similar genres, in the best way. Couldn't put it down!

Love this series a must read. Right from the start this book grabs you love it so much and the whole series is amazing

Thrilling. I read this book in 4 days, loved it and picked it up any chance I could. Looking forward to reading the next one.

Compelling. Absolutely brilliant storyline that captures and enthrals you from beginning to end. Karen Lynch has written a story that can compare to the likes of Cassandra Clare/Richelle Mead and more.

LOVE LOVE LOVE!!. This whole series, couldn't get enough!

Book of the year !!!. This by far the most entertaining book I've read with out a doubt it will be a on the best book list soon!!!!

WOW!! Awesome book! 👍👍👍. Loved reading this book, great storyline and characters. I'm just about to read refuge now and I can't wait!!!!! 👌👌👌


Just couldn’t put it down!. Fantastic read with action, mystery and a little bit of love and romance has me hooked! I feel part of the story and just can’t put it down. Definitely a must read!

Best book!!. This book is one of the BEST books I've ever read they are truly amazing😄😘

Fair. Good setting and world building. Started out with one of the best female characters I read, then became kinda YA traditional and ultimately the plot didn’t interest me.

Love. So obsessed with this book!! Downloaded it expecting twilight themes and I discovered something amazing. Love the Mohiri, such a cool idea, can't wait for Sara to come into her powers in the next book. I couldn't stop reading and I found myself thinking about it all day at work and even having dreams about the characters. Can't wait for the next book, love your work.

Fantastically fantastical. Everything you want in a fantasy world. I couldn't stop reading and can't get enough of these magical People. Absolutely Awesome.

Awesome!!. I loved this book so much and can’t wait to read the rest of the series!! Thanks Karen for sharing this story with the world!! It’s definately one i’ll be reading over and over again!! :D

Amazing!. This book was truly amazing! From the first words, I was hooked. I fell in love with the characters and uniquely amazing storyline, so much so that I read the trilogy in less then three days! Sleep has met its match, and yet, nothing can compete with this addictive and painstakingly beautiful piece of literature!

Just brilliant!. It's not often I come across an author who writes as well as Karen Lynch does in both Relentless and Refuge. Absolutely loved both of these books and cannot wait for the third to be released. The way she writes makes everything seem so real and like this secret supernatural world could truly exist without us ordinary humans being aware of it! I somehow managed to get Relentless and read it, just a few days before Refuge was released, so didn't have much of a wait between them, the wait for the third is going to be hard.

One of my favourite authors!. One of my favourite authors. Anything Karen Lynch writes is great. Thanks for sharing your stories with us!

Amazing! 😍. Loved it from the beginning to the end, the thrill, the action and characters involved are soooo good! Definitely recommend! 👌🏽

Read it!. This series is my favourite, it’s so enticing and amazing I can’t get enough. Definitely suggest to read it.

Enjoyable. Started a bit slowly but as the characters developed it became a really interesting read.

2nd in the trilogy. Unbelievably as good as the last one. Incredible.

One of the best YA series I've read. Takes well known fantasy elements and blends them so well with author's originality. The storyline is excellent - it doesn't fall into the trap of one plot line that annoyingly drags and gives suspense overkill, but charges ahead with more plot and twists! Read, you won't regret it

BEST BOOK EVER!. I read Relentless and Refuge in about a combined 4 days and I am loving it! I can't put them down! I read them once a few weeks ago and I've read bits of them over and over again. I'm honestly worried about what I'm going to do once the series is over. I found it really interesting that there could be a whole other aspect to Earth that humans don't know about. My head spins just thinking about it!

Amazing. I loved this book !!!!!

Fantastic read. I was hooked instantly... now I’m waiting for the next book to be released.

OBSESSED!. I love this series so much. I paid to get every single book so I wouldn’t miss out. I’ve read each book countless times and always pull it out when I want a good read. It’s so well written and full of excitement. Huge props to the author for bringing forward such a good series!!! Hard to find books like these.

Even better!. This book was another great read.. Loved every bit of it, needed sleep badly but, read all of it in one sitting.. Couldn't help myself. :)

Needs to be made into a movie!!. Needs to be made into a movie!!

Great read!. So entertaining that it's difficult to not continue reading through. Love it. I wish it ended with a love story. I recommend it to anyone who is adventurous and desires excitement.

Relentless. I loved this book! Completely fell in love with the characters! It had a perfect balance of magic, action and humour. The dynamic between Sara and Nikolas was lots of fun to watch play out. I highly recommend it to everyone!

Relentless. Overall I was pleasantly surprised with this book. The story line and character development were engaging and I've downloaded the second book for more fun!

Movie worthy. This is an awesome book please make it into a movie or tv series.

Love this book so much. Really loved this one! If you dont get this book, you're truly missing out on one heck of an amazing story!

Awesmazing. Great read! Love that I can never guess how the story will unfold. Love the characters too. The characters were unique, carrying their own personality and trait. All in all, this book caught me like a moth to a flame.

Relentless. Amazing book I hope there will be a book number 2!!! I need to know what happens next!!! Please keep on writing

Excellent start to the series. This story grabbed my attention right from the start and kept it to the very last word. It was imaginative, had a slew of great characters, plenty of action and some hints of romance too. The descriptive writing, believable characters and engaging plot quickly pulls you into a world of excitement, suspense and action. Sara, the main protagonist, is a strong female character with a kind, protective nature and a determined personality and you can not help but like her. Her discovery of her power and origins, the dangers, changes and difficulties she faces endears you to her and you become invested in her life and development. Hints of future romance with the fierce warrior, Nicolas, adds interest and anticipation to the story and I will look forward to seeing how this develops in the rest of the books. The narration on the audiobook was excellent, her tone, pitch and intonation changed with each character giving then all individual voices and personalities. She did a great job of both the male and female characters and hit all the different accents well. I enjoyed this story and look forward to listening to its continuation in the next book.

What an amazing book. <3. It’s currently 3am and I just finished this book and I don’t usually even write reviews of books, but it’s worth it for this one. I don’t usually like books/movies that have anything to do with vampires but honestly this was so amazing. Nikolas and Sara have my goddamn heart.

Wow. Well written and wonderful to read.
