Homeless, streetwise and running away from a past she would rather forget, Francesca Mills is just another face on the streets of London. When a violent encounter leads to a man's death, however, she is forced to leave the harsh world that has become her home and forge a new life elsewhere.

On the run, Frankie unknowingly stumbles across a dangerous secret, a secret so powerful that men will stop at nothing to protect it. She tries to build a new life, but you can only stay anonymous when no one wants to find you. Hunted by both the police and shadowy assailants with powerful connections, the odds are stacked against a woman who will do whatever it takes to protect herself - and those who mean most to her.
