How do I hate thee? Let me count the ways…

Aubrey Cash learned the hard way not to rely on love. After all, Webster Casey, the new boy next door she'd been falling for all summer, stood her up at homecoming in front of everyone with no explanation. Proving her theory that love never lasts seems easy when she's faced with parents whose marriage is falling apart and a best friend who thinks every boy she dates is "the one." But when sparks fly with a boy who turns out to be Webster's cousin, and then Webster himself becomes her lab partner for the rest of senior year, Aubrey finds her theory-and her commitment to stay single-put to the test.

As she navigates the breakdown of her family, the consequences her cynicism has on her relationship with her best friend, and her own confusing but undeniable feelings for Webster, Aubrey has to ask herself: What really happened the night Webster stood her up? And if there are five ways to fall out of love…could there perhaps be even more ways to fall back in?
