Falling in love with your enemy? Impossible. Falling in love with him twice . . .

After an accident leaves Riley Wilson with amnesia, he can recall everything except: the crash that landed him in the hospital, the last year of his life, and having a serious boyfriend. Who happens to be his older brother’s ex-best friend. And the guy he despises more than anyone . . . Learning this information sends Riley spiraling. In what world could someone as sensible and meticulous as Riley have ever willingly agree to go out with Aaron—the arrogant jerk who screwed up his brother’s future? Riley would love nothing more than to start fresh and snip Aaron out of his life. But with his family being cagey about the past, and his memories far out of reach, he realizes Aaron might be the only one willing to help him remember the last year. Despite his brother’s protests, Riley teams up with Aaron to unearth his missing memories—even if it means starting from square one and reenacting every date, every kiss, every “first” they’ve ever had. All Riley has to do is not make the same mistake by falling in love twice.
