Wrong Turn 2: Dead End, by Joe Lynch

Dale Murphy is hosting and producing his own reality T.V show called "The Ultimate Survivalist: The Apocalypse", with six contestants led by Nina Papas, who'll be thrown together for six days in a simulated post-apocalyptic wasteland, and the winner will walk away with $100,000. Located in a remote part of West Virginia, the contestants discover that what they are really fighting for is their survival - against a family of hideously deformed inbred cannibals who plan to ruthlessly butcher them all... Who will survive?
