When young Ehrich Weisz—the future illusionist, Harry Houdini—follows his brother, Dash, through a strange portal, he is thrust into an alternate New York where the immigrants aren't just different ethnicities but different species. He finds work in this strange steampunk world as a Demon Hunter, tracking down dangerous otherworldly visitors that threaten the city's safety, while hiding his own foreign origins. A curious medallion, his only clue to finding his brother, leads Ehrich to a mysterious woman caught up in interdimensional intrigue, and he must learn who to trust as he unravels the truth if he ever wants to find his way home.

Ehrich Weisz, Demon Hunter was introduced to steampunk fans in "Demon Gate."

Amid growing racial tensions, Ehrich searches for Kifo, the man who stole his brother's mind and locked it inside an ancient medallion. He poses as a stage magician to draw out Kifo's next target—the commissioner of Demon Watch. In the wings, an army awaits Kifo to accomplish his mission so interdimensional soldiers can invade New York.
