Straight out of college, five friends with a dream joined forces to build success. Ten years later, their exclusive fitness club, Flatiron Five Fitness, is the hottest destination in Manhattan. People flock to F5F to get fit, to get lucky, and even, to fall in love. The founding partners have been immune to F5F's romantic spell-at least, so far...

Tyler McKay has a plan...
And it doesn't include a serious relationship anytime soon. Between his day job and being a partner at Flatiron 5 Fitness, he's busy investing in the future. But Ty knows that going stag to his sister's wedding will encourage the family matchmakers: he needs a fake date, fast, in self-defense. When the one woman who hates him walks into F5F, Ty knows he's found the perfect candidate-that Shannyn doesn't play by anyone's rules just leaves Ty wanting more...

Shannyn Hawke is done with plans and dreams...
She had her whole life mapped out, but it all went wrong. Now, she's taking care of number one and living in the moment, with no concern for the future. If her college crush wants to trade a fake wedding date for physical satisfaction, Shannyn is in. But just one night proves that Tyler is everything she believes a guy should be, plus he takes it as a challenge to change her mind about him. Shannyn never wants to have her heart broken again, but she's falling hard and fast. Can she remember that it's just for show? Or will Tyler convince Shannyn to take a chance on forever again?
