Publishers Weekly, in its 1999 review, wrote that Bova made the hard science aspects of this novel vivid and appealing. His characters were "less enchanting and the inclusion of a saboteur seems like overkill, since the environment he describes more than capable of destroying anyone for simple carelessness."^[1]
