Proper young ladies in the 1920s don't get dirty, and they certainly don't get into fights. But Colleen's favorite uncle has died under mysterious circumstances, and she wants answers. When a sinister cult comes after her, she pushes back - hard.

Soon she's running for her life, hunted by the cult of Katharis and aided by a secret government agency. It will take all of her courage, all of her strength, and every steam-powered weapon she can devise to keep her alive long enough to unravel the mystery of her uncle's death.

The cult thinks she knows her uncle's secrets. They'll do anything, hurt anyone, to make her talk. But they've made a grave mistake. Colleen is going to take the fight to them, again and again, until the people she cares about are safe - or have been avenged.
