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.

Relentless (Karen Lynch) Book Reviews

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!.Score: 4/5

RelentlessThis 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..Score: 3/5

WowIt’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..Score: 5/5

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!!!!!.Score: 5/5

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..Score: 4/5

Realism in a fantasyThis 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!.Score: 5/5

Eh 2.5Giving 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.

AMAZINGThis 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!.Score: 5/5

Excellent start to the seriesThis 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..Score: 5/5
