It's The Lord of the Flies meets The Ruins, when a clinical trial for a new diet drug goes disastrously awry and a group of young survivors is left to deal with the consequences. Five boys and their scoutmaster are dropped off by boat on small, deserted Falstaff Island, Canada, for a weekend of campfires, survival lessons, and merit awards. But the experience takes a dark turn when a severely gaunt man in tatters appears on their cabin doorstep. Before the night is through, this stranger will end up infecting one of the troop’s own with a ravenous parasite that’s straight out of their worst nightmares. It’s not long before the harrowing situation turns into a desperate struggle for survival against the elements, the mysterious plague...and eventually, each other. Author Nick Cutter has crafted a visceral burn of a novel that deftly combines boldly drawn characters with a fantastically rendered narrative--a terrifying and unforgettable story told in the epistolary format that will captivate audiences everywhere.
