A dark journey toward redemption through a bleak but beautifully-rendered world where monsters are real—and the worst of them are us.
Philadelphia, 1806. Tales of water ghosts haunt the docks, violence stalks the streets, and Indian uprisings fill the news. Kellen Ward and Vincent Bradley are down on their luck and low on options. When Vincent is offered a job outside the city, he has to take it—even though it means leaving Kellen behind. 
Alone in Philadelphia, Kellen struggles to stay a step ahead of a murderous supernatural threat and dodges her growing feelings for a new and potentially dangerous man in her life. Meanwhile, Vincent is caught up in the plots of a charismatic military leader with big plans for the men he's recruited—plans which include experimental and irreversible changes to their bodies and minds that might make more of them than they ever dreamed.
If it doesn't kill them—and everyone else.
