Like Fracassi’s previous novel, Gothic, Boys in the Valley involves devil-worship and demonic possession. The publisher’s pithy tagline describes Boys in the Valley as “The Exorcist meets Lord of the Flies, by way of Midnight Mass.” Similarities to The Exorcism are obvious, and both the absence of effective adult supervision and the pervasive child-on-child brutality certainly bring to mind Lord of the Flies. But despite being—at its heart—a religious horror novel, I would also recommend it to fans of John Carpenter’s The Thing (1982).
