Imagine finding yourself divorced and penniless, with no skills and a teenage daughter to support. What if the only way to survive was to do things you never thought possible? These are questions Sally Benedict has never thought about. Married to a successful businessman, she's always been a bit of a dreamer. Until now. Her sister, Zoë, is a detective in the city of Bath. She is fiercely independent, loves her job, and oozes self-confidence in spite of a crippling secret that dates back twenty years and which--if exposed--may destroy her. The two women haven't seen each other for almost twenty years, but the horrific murder of a teenage girl is about to change that. Then Sally's daughter gets into trouble, and Sally suddenly needs cash--lots of it--fast. With no one to help her, she is forced into a criminal world of extreme pornography and illegal drugs; a world in which teenage girls go missing. Two sisters intent on survival find themselves confronting situations they never expected to face . . . until one of the sisters does something so horrific and desperate that there's no way back.
