Subhuman (Unit 51)

They are not human.At a research station in Antarctica, five of the world's top scientists have been brought together to solve one of the greatest mysteries in human history. Their subject, however, is anything but human . . . They are not natural.Deep beneath the ice, the submerged ruins of a lost civilization hold the key to the strange mutations that each scientist has encountered across the globe: A misshapen skull in Russia. The grotesque carvings of a lost race in Peru. The mummified remains of a humanoid monstrosity in Egypt . . . They are not friendly.When a series of sound waves trigger the ancient organisms, a new kind of evolution begins. Latching onto a human host-crossbreeding with human DNA-a long-extinct life form is reborn. Its kind has not walked the earth for thousands of years. Its instincts are fiercer, more savage, than any predator alive. And its prey are the scientists who unleashed it, the humans who spawned it, and the tender living flesh on which it feeds . . .
