The next exciting chapter in the saga of the man-made creature Number Thirteen begins! Having escaped captivity within the British military compound on the tropical island of Professor Maxon, Townsend Harper, Jr., and Virginia Maxon have every intention of sailing away from the island and never revealing the secrets of the scientific experiments being conducted there... Experiments into the creation of human life. But things are about to take an even darker and more deadly turn, as the nightmarish creations of Professor Vogel have also escaped, and now prowl the jungle in search of human flesh! The couple's only hope for survival is Otto, the hulking man-monster once called Number Thirteen, but can they trust a creature with the mind of a child and a face so hideous that we can't even reveal it?
