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.

Q: Are these new characters?

A:Yes! Hayes and Maren are brand new characters you’ve never met and I can’t wait to introduce you.

Q:Is this part of a series?

A: This is book 1 in a new series about a group of male best friends who own an adult toy company. Get ready for lots of shenanigans, feels, and a swoonworthy bromance. Each book can be read as a standalone.

    This 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.

    The 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.
  • A great start to the series!

    By RowenaB10
    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.
  • How will her brother feel about their relationship?

    By lynn71149
    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.

  • 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!

    Cute story but felt rushed. It was nice reading a storyline without stifling drama.
  • Charming!

    By Astroyic
    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!
