Hannah Dexter is a nobody, ridiculed at school by golden girl Nikki Drummond and bored at home. But in their junior year of high school, Nikki's boyfriend walks into the woods and shoots himself, a discovery that sends tremors through the conservative town, already unnerved by growing rumours of Satanic workship. In the wake of the suicide, Hannah finds herself befriending new girl Lacey and soon the pair are inseparable, bonded by their shared hatred of Nikki. Lacey transforms good girl Hannah into Dex, a Doc Marten-wearing Kurt Cobain fan, who is up for any challenge Lacey throws at her. As a web of love, loyalty, betrayal, sex and violence builds up around the girls, Lacey and Dex bring their combined wills to bear on the community in which they live. Unconcerned by the mounting discomfort that their lust for chaos and rebellion causes the inhabitants of their parochial small town, they think they are invulnerable. But Lacey has a secret, about life before Dex. And it's a secret that will change everything.
