The Western Territories, 1880. For four years, Civil War veteran and former U.S. Cavalry Captain Jonas P. Hollister has been rotting in a prison cell at Fort Leavenworth, Kansas. His crime: lying about the loss of eleven soldiers under his command... who he claims were slaughtered by a band of nonhuman, blood-drinking demons.

But now a famous visitor, the detective Allan Pinkerton, has arrived with an order for Hollister's release. The brutal murder of a group of Colorado miners in a fashion frighteningly similar to the deaths of Hollister's men has leant new credence to his wild tale. And suddenly Jonas Hollister finds himself on a quest both dangerous and dark?joining forces with Pinkerton, the gunsmith Oliver Winchester, an ex-fellow prisoner, a woman of mystery, and a foreigner named Abraham Van Helsing, who knows many things about the monsters of the night?and riding hell for leather toward an epic confrontation... with the undead.
