"Please help me. Anyone. Gods, devils, angels, demons... whoever is out there. Please, please, I need help." Little does Dawn, a woman with a troubled past whose hard-won life is on the verge of crashing down, know that an entire world of gods, devils, angels, and demons is indeed out there, and their sights are set on her. Just as Dawn is unknowingly calling supernatural forces to her quiet Salisbury home, Lucifer and his Kings of Hell walk among us and race to resolve a strange and unknown threat that could upend the balance of both the human and divine realms. Hot on their tails is the archangel Michael, under the guise of an FBI consultant tasked with apprehending an unusual serial killer with an occult obsession. As all their paths intersect, the fate of the world hangs in the balance.
