The Sorceress, Mairin, and her demon lover, Bane, are on the run for crimes of foul magic and murder. After centuries of flight, they take refuge at Felmore House, a brooding mansion in the high desert of Arizona where a dimensional gate offers hope deep within the canyon of Devil's Maw. Their once great magic is failing and the hunters on their trail are drawing ever closer. Worse, the all consuming passion that once sustained them has become a fragile, perilous thread of suspicion and mistrust. The household of Felmore House has served their masters for three generations. Teenager Sissy is the newest addition to the House, abandoned by her family and forced into servitude. She soon learns that intrigue and conspiracy are not limited to the sorceress and her demon, but can't avoid being swept into the tangled web of a House at war with itself. One wrong step could cost her life. And her soul.
