A helicopter crashes with a young judge and his family onboard. The wreckage reveals his and his wife's mutilated bodies but not their daughter's. An insurance investigator attempts to resolve this bizarre case, and in the process he discovers a merciless race of beings who never sleep... Fast-moving and highly readable, this novel features some very graphic violence and is definitely not for the squeamish. Masterton utilizes the American setting well, managing to conjure up a genuinely scary portrait of an alien-like race which should (quite literally) get your adrenaline pumping.
