Now she just wants to keep her head down, but her boyfriend has a dark secret of his own¿one involving an apparent stranger who is destitute and despised. Lucie alone knows the young men's deadly connection, and even as the knowledge leads her to make a grave mistake, she can trust no one with the truth. Blood and secrets alike spill out when revolution erupts. With both halves of the city burning, and mercy nowhere to be found, can Lucie save either boy¿or herself?
