Metropolis by Elizabeth Gaffney

On a freezing night in the middle of winter, Gaffney’s nameless hero is suddenly awakened by a fire in P. T. Barnum’s stable, where he works and sleeps, and soon finds himself at the center of a citywide arson investigation.

Determined to clear his name and realize the dreams that inspired his hazardous voyage across the Atlantic, he will change his identity many times, find himself mixed up with one of the city’s toughest and most enterprising gangs, and fall in love with a smart, headstrong, and beautiful young woman. Buffeted by the forces of fate, hate, luck, and passion, our hero struggles to build a life–just to stay alive–in a country that at first held so much promise for him.
