Nora Reid believes scientific laws control everything, even love. With her grandparents' epic first kiss story cemented in her brain, Nora develops a hypothesis she's determined to prove: for each person in the world, there is exactly one other person, and at first kiss, they'll experience an immediate and intense reaction.

But after four years of zero-reaction kisses, she comes up with a new theory: maybe that pesky crush on her stunningly hot best friend Eli Costas is skewing her results.

She needs to get rid of him, and fast.

Eli Costas is an injury-prone lacrosse star with a problem—the one chance he had at winning over the girl next door resulted in the most epically sucktastic first kiss ever. And now she's . . . trying to get rid of him? Hell no. It's time to disprove her theory and show her exactly what she's missing.

Game. On.
