As the proprietor of Disenchanted & Co. in a steampunk version of America, Charmian "Kit" Kittredge makes her living solving magical crimes. But when a snobbish lady begs for help, saving her reputation might very well cost Kit her life.

Doing a favor for deathmage Lucien Dredmore, Kit agrees to interview a newly widowed lady as a potential client. Upon meeting, however, she learns that the woman in question is none other than Lady Eugenia Bestly, president of the Rumsen Ladies Decency Society--someone who once led a vicious campaign to ruin Kit's life. Ironically Lady Bestly now lives in fear herself, for the press is about to unmask her husband as the savage "Wolfman" who died while terrorizing the city.

As monstrous rampages continue to occur, Kit soon determines there is more than one Wolfman, and that they may themselves be victims of evil players. While avoiding both mechanized assassins and attempts by Dredmore and Chief Inspector Tom Doyle to take her under their protection, Kit follows a tangled path that leads from a prestigious gentlemen's club fronting a hellish secret to a vengeful native tribe and dangerous, ancient magics.
