Something is wrong on Danforth Research Station. Orphaned children disappear from the slum-like "lowers," while fearsome masked guards prowl the corridors. Death lurks around every corner, waiting to swallow the unwary.

When a mysterious girl named Carter comes to Danforth, it's up to a boy known only as "Silence" to teach her to survive. But Carter has secrets of her own, and the horror within may be far greater than the horror without.
