“The Troop scared the hell out of me, and I couldn’t put it down. This is old-school horror at its best.” —Stephen King
This “grim microcosm of terror and desperation haunting” (Christopher Golden, New York Times bestselling author) follows a scout troop on a terrifying fight for survival when they come across a mysterious—and deadly—stranger in the Canadian wilderness.

Once every year, Scoutmaster Tim Riggs leads a troop of boys into the Canadian wilderness for a weekend camping trip—a tradition as comforting and reliable as a good ghost story around a roaring bonfire.

But when an unexpected intruder stumbles upon their campsite—shockingly thin, disturbingly pale, and voraciously hungry—Tim and the boys are exposed to something far more frightening than any tale of terror. The human carrier of a bioengineered nightmare. A horror that spreads faster than fear.

A harrowing struggle for survival with no escape from the elements, the infected…or one another. Part Lord of the Flies, part 28 Days Later—and all-consuming—this tightly written, edge-of-your-seat thriller takes you deep into the heart of darkness, where fear feeds on sanity…and terror hungers for more.
