A crew goes out into space to carry out research experiments in zero gravity, but one by one they contract a deadly disease... This is nothing like most of Tess Gerritsen's other books, verging more towards a sci-fi horror than a medical thriller. It's horrific, dark, gory and compelling - I loved it. A refreshing change from her usual work, and again goes to show her versatility as a writer.

This is a chilling study of what would happen if an unknown infective agent were dabbled with and affected by the absence of gravity. The supposed outcome is potentially terrifying. There is of course the usual involvemnt of the military, Nasa fighting against time and the military, the underdog engineering firm, and the all-American hero out to save the woman he loves. This woman is the hero of the piece, feisty, smart and of course the answer to everyone's prayers. As ever with Gerritsen's work there is an impressive attention to detail, some superb science fiction mixed with science speculation and indeed science fact. Frighteninly good stuff and all too plausible, it will definitley have you thinking about the possibilities of such an organism.

Very different from her other books - but still a good read!
