"A crazy-good, balls-to-the-wall horror novel . . . it's full throttle from the first pages." -Joe Hill

"This is the kind of great, big, epic horror novel we got back in the '80s that came out swinging for the fences and left everything on the field. Welcome back, you shaggy, bloody monster of a book!" -Grady Hendrix
