With a body in the river and a series of spacesuit failures, Nathan Spring is unconvinced by the machine's verdict of accidental death. And instinct is telling him to pursue it even if it means laying his own life on the line.

When a mystery kidnapper steals three frozen embryos from Moonbase, the crime seems motiveless. Then their mother turns out to be the wife of an infamous arms dealer with a list of henchmen and enemies a mile long. With the ransom deadline approaching, Nathan is finding out what it's really like to race against time to save lives.
