This is not a story of bad things happening to bad girls. I say this because I know you, Dex, and I know how you think.
I'm going to tell you a story, and this time, it will be the truth.
Hannah Dexter is a nobody, ridiculed and isolated at school by golden girl Nikki Drummond. But in their junior year of high school, Nikki's boyfriend walks into the woods and shoots himself. In the wake of the suicide, Hannah befriends new girl Lacey and soon the pair are inseparable, bonded by their shared hatred of Nikki.
Lacey transforms good girl Hannah into Dex who is up for any challenge Lacey throws at her. The two girls bring their combined wills to bear on the community in which they live and think they are invulnerable.
But Lacey has a secret, about life before her better half, and it's a secret that will change everything . . .
