Watson Publishers Weekly (starred review) A road tour of American-Gothic grotesquery. Effective, literate, nightmarish. --S.J. Watson The Sunday Telegraph (UK) It's impossible to ignore the devils and demons who have a tangible presence in this story, but the novel's deeper pleasure comes from the analysis Ullman applies to these horrors . . .

This artful literary exploration of evil's manifestation makes for a sophisticated horror tale. --S.J. Watson Kirkus Reviews Smart, thrilling, and utterly unnerving.
