Falling Away by Penelope Douglas

Jaxon is the guy she's supposed to avoid . . . 

K. C. Carter has always followed the rules - until this year, when a mistake leaves her the talk of her college campus and her carefully arranged life comes crashing to a halt. Now she's stuck in her small hometown for the summer to complete her court-ordered community service, and to make matters worse, trouble is living right next door.

K.C. is the girl he won't let get away . . . 

Jaxon Trent is the worst kind of temptation and exactly what K.C. was supposed to stay away from in high school. But he never forgot her. She was the one girl who wouldn't give him the time of day and the only one to ever say no. Fate has brought K.C. back into his life - except what he thought was a great twist of luck turns out to be too close for comfort. As they grow closer, he discovers that convincing K.C. to get out from her mother's shadow is hard, but revealing the darkest parts of his soul is nearly impossible.

'I read this book in one sitting. Rival was as gripping as it was sexy!' - Colleen Hoover 

Quote from Penelope Douglas:

Bully was my love. 
Until You was my responsibility.
Rival was my pleasure.

But Falling Away was my destiny. 

Every whisper, every breath, every kiss, and every word came from my gut. This is the book I'm most proud of.
