In a city where shadows breathe and the night fights back, Elias Mercer and Mara Vance confront a rising darkness that adapts and learns from every strike.

With every battle escalating, survival demands courage, cunning, and trust because in the dark, nothing is what it seems, and the city’s fate hangs in the balance.
