"The best American horror novel since Stephen King’s The Shining. This brilliant novel--completely of the moment, yet utterly timeless--deserves to become a classic."

--The Philadelphia Inquirer

"A tour de force of terror, a novel that seduces, shocks and dares you to keep reading--and never relents, not even on its final page."

--The Washington Post Book World
