"Hard to put down, impossible to forget... subtle and disturbing" Today

Lucy Ashdown is a girl with a mission - to find the driver who ran down and killed her sister Christine. Now she has a lead and she's off to London.

Disgraced Detective Joe Lucas is as dedicated as Lucy. His aim is to bring her home. By any means necessary.

Stepping into her sister's shoes, this small-town girl is thrust into a terrifying night journey of deceit, danger, and degradation. By recreating her sister's life, she unwittingly heads toward her sister's fate; and even as she believes that she's closing in on the murderer, the murderer is closing in on her.
