Before Quinn Ryan was in love with Jamie Rudawski, she loved Jamie Rudawski, who was her best friend. But when Jamie dumps Quinn a month before their senior year, Quinn is suddenly girlfriend-less and best friend-less.

Enter a new crush: Ruby Ocampo, the gorgeous and rich lead singer of the popular band Sweets, who's just broken up with her on-again, off-again boyfriend. Quinn's always only wanted to be with Jamie, but if Jamie no longer wants to be with her, why can't Quinn go all in on Ruby? But the closer Quinn grows to Ruby, the more she misses Jamie, and the more (she thinks) Jamie misses her. Who says your first love can't be your second love, too?
