A detective haunted by his past. A predator constrained by centuries of secrets. When a series of inexplicable deaths and drugs rocks the city, their paths collide in a forced alliance neither wants. She views him as disposable. He views her as the enemy. Yet, to stop a terror that exploits the very shadows they inhabit, these two sworn adversaries must rely on their mutual disdain to stay alive. A gritty, high-stakes investigation where mistrust is the only bond.
