"It begins like a campfire story: Five boys and a grownup went into the woods... It ends in madness and murder. And worse... Once a year, scoutmaster Tim Riggs leads a troop of boys into the Canadian wilderness for a three-day camping trip - a tradition as comforting and reliable as a good ghost story and 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. An inexplicable horror that spreads faster than fear. A harrowing struggle for survival that will pit the troop against the elements, the infected...and one another. Part Lord of the Flies, part 28 Days Later - and all-consuming - this tightly written, edge-of-your-seat thriller will take readers deep into the heart of darkness and close to the edge of sanity." -- Publisher.
