One needs saving. The other needs justice.

The girl with no past.

Six years ago, Evie Cormac was discovered, filthy and half-starved, hiding in a secret room in the aftermath of a shocking crime. Now approaching adulthood, Evie is damaged, self-destructive and has never revealed her true identity.

The boy who survived.

Forensic psychologist Cyrus Haven, a man haunted by his own past, is investigating the death of champion figure-skater Jodie Sheehan. When Cyrus is called upon to assess Evie, she threatens to disrupt the case and destroy his ordered life. Because Evie has a unique and dangerous gift – she knows when someone is lying. And nobody is telling the truth.

Good Girl, Bad Girl is an unnerving psychological thriller from one of the greatest crime writers of today.
