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.
