19-year-old Cooper has a plan: drive Grandpa's car from Illinois to California and earn some cash. Then Jon—his brother's best friend and Cooper's archenemy—is assigned as his unwilling babysitter. Cooper is livid. Yeah, he used to have a crush on Jon, but that was before Jon did something unforgivable. Jon knows exactly why keeping his distance from Cooper matters. One reckless decision a year ago proved that some lines should never be crossed. Especially not with Cooper, the one person Jon would walk through fire for. He promised Cooper's family to keep him safe, but if anyone is a danger to Cooper, it's Jon himself. When biology intervenes and things get heated, will Jon and Cooper finally admit how they really feel?
