A horrific take on the true story of the Winchester haunted house and one woman's mission to wash away the blood curse of the Winchester rifle from claiming her own life and soul.

This is a tale about guilt, ghosts, and guns...of how fortune brings misfortune, as a grim and determined woman oversees the construction of a house twenty four hours a day for twenty years with the simple motto of keep busy building or get busy dying.

"Peter Tomasi and Ian Bertram make you want to sleep with the lights on after reading this tale of horror and dread that wraps you around the throat and doesn't let go. There's a price for everything, and we are reminded of that in the most entertaining, and disturbing, way."
- Geoff Johns (Justice League)

"House of Penance is Peter Tomasi's finest work to date, a haunting, macabre experience that will stay with any thoughtful reader long after its conclusion. A fine tale well told, and highly recommended."
-Garth Ennis (Preacher)
