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, Michael Robotham, bestselling author of The Other Wife and The Secrets She Keeps.
