Thirteen years ago, Adair Ellis told a little lie. A lie with big consequences for high school heartthrob Josh Cohen, a guy who never knew Adair existed. She vowed no more lies, never again, but when she and Josh meet in Race of Hearts, a singles event, she becomes the queen of deceit.

As they compete against other couples in sexy, romantic challenges, the unrequited crush she had on Josh in high school comes back with a vengeance. And this time, the passion is mutual.

She'll do anything to keep the past buried, even if it tears her apart along the way. But someone knows what she did and that someone thinks she should pay.
