The Boyfriend Effect

A sexy new series of standalone romances from New York Times bestselling author Kendall Ryan. 

I’m not boyfriend material.

If a trail of broken hearts and a piss-poor record of failed relationships have taught me anything, it’s this. My buddies are happy to give me shit about my latest breakup from here to next Sunday. Thanks, but I’d rather have a root canal.

And a vasectomy.

At the same time.

Relief comes in an unlikely package—the gorgeous and feisty Maren. She just so happens to be my best friend’s sister, so that’s not awkward at all.

But I’m a man on a mission, and Maren is down to teach me all the ways I’ve been failing as a boyfriend. Apparently, there are many. And it’s all very informative—until I start to catch feelings.

Now it’s not just my reputation on the line, but my heart too.

New Series!!What a swoony, fantastic start to a new series by Kendall Ryan! This is the story of Maren and Hayes. There has been chemistry for years. Hayes has watched Maren grown up and his "brotherly" feelings have changed. Hayes has had such bad track record with relationships and women.  He can't seem to figure out what he's doing wrong.   I loved Maren's personality and her character strength, she knows what she wants and will use what she has to get it.  She loves her job and will do anything to save it. I loved the introduction to the new cast of characters and the business that they founded!  The dialogue is witty and the smexy times are so hawt! Swoon overload with this story! I can't wait to see the next story in this series!.Bibliophile ChloeScore: 5/5

Not for meI’m sorry—are the rest of these reviews paid reviews? This chick has to rack her brain to figure out a way to get donations for her job. The guy comes in and recommends a fundraiser and it’s like he’s the smartest man in the universe to her????? A fundraiser. Who woulda thunk it. Also, doesn’t this facility charge residents for living there?? How is it that one person pulls their donation and they now only have enough funds for one more month of payroll? And yet a fundraiser charging a couple hundred a head is going to save them??? There are too many other brother’s best friend books out there to make me want to continue this one..GrizzlyclarkScore: 1/5

Charming!I always find it amazing how Kendall Ryan tells a story. Once I start reading I am completely lost to it. How it is always fresh and engaging, sexy and fun. There are always such great characters that I would want to be friends with and hang out with. She is truly a fantastic story teller. So I loved this, I think that is obvious. Hayes was full of personality and charm as well as some great moves, I couldn’t get enough. Maren was great also. And both of them are torn and hiding some serious feelings for one another. YUM!! This was so much fun, entertaining, playful and I could feel the want and need between the two. Their sexual tension adds sizzle to every scene and there was this passionate connection that created so much heat. This had me practically drooling with anticipation from one page to the next... So Awesome! As well as my favorite trope BFF’s little sister! Sigh! My fingers were on fire flying through the pages as quick as I could. Also loved all the secondary characters and how they helped this relationship along. Even when some didn’t know they were, There were so many funny parts in this. I burst out laughing at times. And there was a great balance of entertaining, sexy and emotions throughout. Such a fantastic story. Waiting anxiously to read the rest of this series and see these characters find their journey to true love. What a way to start a new Series!! This made my heart feel full, and happy!.AstroyicScore: 5/5

The Boyfriend EffectThis forbidden little sister of my best friend romance was sweetly sexy. Hayes was a serial monogamist, his constant flow of girlfriends ending in breakups had him wondering if he would ever settle down. I liked the way he finally realized that he was hung up on Maren almost his whole life. As with this genre, the climax built up for the big reveal to Maren’s brother. Enjoyable and well written.

Amazing!I loved this book! Can’t wait to read the others in this Series and more from this Author!.Till0105Score: 5/5

Absolutely lovedThe opening sequence is down right hilarious, I could not stop laughing throughout this entire scene. This is a great start to this new series, looking forward to the rest of the friend group find their other halves. The storyline between Maren and Hayes is fantastic, with great chemistry and a wonderful friendship to base their growing romance. There were a few unexpected surprises that I did not see coming, which just adds more depth not only to the characters, but keeps the reader interested in its entirety. Loved the ending as it wrapped up nicely and you get insight as to who is next. I am voluntarily leaving a review for this book that I received free..Mchappy99Score: 5/5

Great!!Hayes has been fighting his attraction to his best friend’s sister for years. When his friend asks him to check on her he reluctantly goes to her apartment. Maren has fought her. Attraction to her older brother’s friend. When he gives her a chance to help her workplace she can’t resist. Super spicy forbidden romance. Hayes was a likable player. Maren was just sweet. Great build up of tension. Wonderful side characters. From Hayes business partners, to the family members, to the people at Maren’s work they all added to the story. A great read!.RlamltScore: 5/5

How will her brother feel about their relationship?Hayes is a workaholic who lives with his grandma and owns an adult toy company with some friends. He has known Maren/Dove, 25, since she was in kindergarten and she is his best friend’s sister. Hayes has never had a long term girlfriend and has been attracted to Dove, but didn’t date her because of his friendship with her brother. Dove is a social worker who works at a nursing home and Hayes helps her plan a fundraiser and she becomes even more attracted to him. When the group of friends takes a trip to Haley’s grandmother’s lake house they end up sleeping together but then guilt takes over. Will Hayes and Dove talk to her brother about their feelings? Can they find happiness together? I loved this story about falling for your best friend’s sister. They had known each other for years but never realized the connection. The author did a great job showing how their relationship developed from friends to more and how the role their families played. I loved the epilogue and highly recommend this book.

Frisky and Risky and Sweet and SexyThere's something just so appealing about a little bit of the forbidden, like, say, falling for your best friend's sister. That apparently goes against some 'bro code' (don't ask me why, I don't get it), and that is somehow like an undeniable magnetic pull in the world of romance. Case in point, THE BOYFRIEND EFFECT, the first book in the Frisky Business series by author Kendall Ryan. This is not a new trope for Kendall, but she does it very well, so I'm not complaining. I mean, it isn't hard to like Hayes Ellison. He's not had the best luck in the world of dating, and, also, he's harboring a years-long crush on his best friend and business partner's little sister. Danger, Will Robinson...what's a guy to do except give it the old college try, even though he's veritably dying to date the heck out of this girl. Luckily, Hayes is not alone in his feelings, because Maren has a little crush of her own, and it doesn't take much more than realizing this for the ball to get rolling, and sparks to fly. It's sweet, and sexy, and love the way that Kendall does so well. This is a fun and easy read, but I have to admit to really wanting to get to Wolfie's story, because he is a hoot. In the meantime, get the ball rolling with THE BOYFRIEND EFFECT and enjoy your introduction to the friskiest business around. ❤️.CoffeegoddesstmkScore: 4/5

BadIt structure of the book and the wording make it seem like it’s written by a love sick 15 year old. It feels stale and emotionless. I cringe whenever the characters talk about their “sexual tension” about the other character. The characters are shallow and 2 dimensional..DjagffbdbalScore: 2/5

A great start to the series!A great start to the Frisky Business series! We have a brothers best friends/ friend to lovers that fans of this genre will go gaga over. Maren and Hayes story is so heart felt, with just a simple touch and a heated glance they sizzle. When they take their relationship to a delicious new level it was so worth the wait. A great storyline with likable characters made this a definite must read. I can’t wait for Penelope and Wolfe story..RowenaB10Score: 5/5

Entertaining Read4.5 Stars for The Boyfriend Effect ( Frisky Business, Book 1) If this book is anything to go by the Frisky Business Series is going to be a fun, entertaining ride. Hayes and Maren have known each other for what seems like forever, he is her brothers best friend and that means he should be off limits but we can’t always control our hearts and her heart wants him..... Hayes is not boyfriend material but it’s a Maren he goes to when he needs advice on changing his ways and that’s when the fun and games begin..... What do you do when you both realise the person you want is right in front of you, do you risk the friendship and hope it withstands the journey you are about to embark on and what about crossing the line with your best friends sister are you prepared to risk that friendship as well ....guess you need to read the book to find this out. This book ticked my boxes, the banter is witty, the chemistry is sizzling but it was the friendships that took this book up a notch for me. I’m excited for this series and can’t wait for the next instalment. Great start to a new series from the very talented Ms Ryan.Jaxwright57Score: 5/5

FunThis was a fun, quick read that ticked quite a few boxes for me. Hayes is Maren’s brothers best friend and even though she knows she shouldn’t be attracted to him, she is. This is a friends to lovers story that was entertaining. The attraction that sizzles between them crackles the air and is hard to resist. Hayes has a reputation as a not very good boyfriend so when he turns to Maren for advice you know that there is going to be some fun times ahead. However what happens when feelings come in to play? Do they take a chance and hope that the friendship they have withstands a relationship? Their banter and friendship was genuine and I loved that their journey to love started with friendship..Erin Lewis aka Maimeo'sScore: 4/5

The Boyfriend Effect.I loved this story it’s a best friends little sister romance it’s about Hayes and Maren. Hayes has had so many failed relationships he doesn’t know what he’s doing wrong but he can’t put his heart into any relationship until he gets all tangled up with Maren who has such a sweet soul and kind heart and a massive crush on Hayes. I’m not going to get too much into this story but it’s funny, sweet and sexy I loved Hayes’s grandmother and I highly recommend this book it’s definitely well worth the read..Caroline DoigScore: 5/5

Great readEnjoyed The Boyfriend Effect immensely. Sympathetic to both parties on their previous dating experiences- haven’t we all done something similar, usually until the right person crosses our paths. Love the industry the boys work in, lots of use of imagination and fun takes to tell..DragonlassScore: 5/5

So much to love about this book!You know when you read a book with such ease and you genuinely feel happy? This book has it in spades. I tell you Maren is this caring woman with an absolute heart of gold. When her work is having financial difficulties, her brothers best friend Hayes steps up to the plate with ideas to help. Lets just say Hayes and Maren are fire. They have such sizzling chemistry and their banter is amazing. I just loved the ease of friendship and especially Hayes grandma, shes wonderful. I think Hayes could charm anyone, hes just that type of man but with his past relationships something seems to always go wrong, what is it about Maren that makes everything feel right? Hes conflicted but in his heart of hearts he has to know what is right. Can these two become more especially when someone doesn’t know and might not approve. Only one way to find out. Go grab your copy to find out! So much to love about this book!.Marina SkinnerScore: 5/5

An addictive and sexy romcomA friends to lovers/best friend’s sister romance which I absolutely loved. It was sexy, it was funny (oh so funny), and it was sweet. Hayes Ellison has known Maren Cox pretty much her whole life. He’s been best friends with her brother since third grade, so when she’s all grown up and filled out in all the right places, she’s unattainable, yet it would appear they’ve not got that memo, oh no, what they’ve both got is the hots for each other. Add in Hayes’ grandma Rosie, and her new ‘friend’ Don, and what a wonderful read we have. All the scenes with Rosie and Don p in had me laughing my socks off, truly hilarious. Hayes reaction to them was just THAT funny. That aside, he was also sweet, sensitive and oh so sexy. He thought he wasn’t boyfriend material, it turns out he’s just not met ‘the one’. A truly addictive, sexy and enjoyable romcom. I loved it. I received an advanced copy of this book. This is my honest review..LilleyLoohLahScore: 5/5

FantasticFirst time reading a book by this author and I wasn’t disappointed! Hayes falls for the forbidden, his best friends sister Maren. He struggles with keeping his feelings intact, but she may be exactly what he needs. Such a really easy read with humour, the forbidden, love and romance.

Move over Tom, there’s a new boy in town!!!The Boyfriend Effect is the first in a new series, ‘Frisky Business’, by Kendall Ryan. It had me giggling from the opening chapters and that light-hearted feeling stayed with the story throughout. Maren and Hayes were a sweet, and sexy couple. Maren’s held a hidden candle for Hayes for years but never had the opportunity to let him ‘see’ her. Once he did, it was all hands on deck, or counter, lol. I loved these two, and the secondary characters were pretty amazing too, especially the elderly variety..CeeCeeHoustonScore: 4/5
