An elderly widow is found dead in her cottage, on the West Coast of Ireland. The death should have been unremarkable, but the events that unfold in the days following, change her granddaughter's life forever.

Preparing for the funeral Lucy White stumbles across a secret she was never supposed to unearth. She was born into the top echelons of a New York crime family. In 1984 her mother testified against the mob and entered a witness protection program.

Lucy's ordinary life is suddenly turned on its axis. Her crusade to find the family she never knew about gets her trapped in the New York criminal underworld until the FBI, deploy for a second time the resources of WITSEC and extract her from the mob's grip, back to a life of safety and anonymity, like her mother decades earlier.
