"For most people, the past is history. For witness protection officer Ros Gilet, it is a threat. And it is a threat that's just become all too active as a copycat killing in the present brings back from the past characters who are no longer supposed to exist. Real life ghosts in fact-- but who are these ghosts? And what do they want? In her search to find out, Ros will uncover a hidden story that spells disaster not only for herself, but or those closest to her. But in a story that comes to more and more resemble a 3D chess puzzle, two questions begin to dominate-- How far is Ros prepared to go to safeguard her clients? And why is her past as much of a mystery as the people she's chosen to protect?" --
