Watchers in the Night (Guardians of the Night)
Gray never stopped loving Carolyn, but the fateful night of his bachelor party changed his life forever. He would do anything to shield her from the world he now inhabits, a world where Killers hunt the night and Guardians hunt the Killers—and he tries to walk a third path, refusing to become one or the other. But when a serial killer called the Broad Street Banger seems to be targeting Caroline, Gray risks everything to keep her safe—even as the Guardians consider him the prime suspect.
Caught in an escalating game of cat and mouse, Gray and Carolyn must forget the passion they once knew if they ever hope to evade the Guardians and find the real killer.
