Seventeen-year-old Sadie is tired of being a good girl.

Her Career Aptitude Test results say she's ideally suited for a career in the clergy (a.k.a. a nun), and on top of that, she receives yet another rejection. An aspiring dancer/choreographer, Sadie dreams of being featured on Dancer's Edge-but they say she's too sweet, needs more life experience. Her BFF, Kyle, and her oldest friend, seventy-nine-year-old Betty, agree: Sadie is in desperate need of a life makeover.

But she'll need a coach.

Sadie doesn't lie, cheat, or steal-heck she doesn't even curse (part of the reason she hasn't checked off anything on her "Carpe Diem List"). Sadie doesn't know the first thing about being bad. But Kyle's twin brother, Colton, does. And he's willing to teach Sadie on one condition: she has to do everything he says for the next month.

A dazzling first kiss, two smokin' hot brothers, and a bet that changes everything. In this enemies-to-more YA romance, Sadie learns that breaking the rules can be fun-especially when it leads to happily-ever-after.
