Tess Gerritsen used to be a doctor, so it comes as no great surprise that the medical aspects of her latest thriller are absolutely convincing -- even if most of the action happens in where few doctors have ever practiced -- outer space.
Dr. Emma Watson and five other hand-picked astronauts are about to take part in the trip of a lifetime -- studying living creatures in space. But an alien life form, found in the deepest crevices of the ocean floor, is accidentally brought aboard the shuttle Atlantis. This mutated alien life form makes the creatures in Aliens look like backyard pets.
Soon the crew are suffering severe stomach pains, violent convulsions, and eyes so bloodshot that a gallon of Murine wouldn't help, brilliantly describes the difficulties of treating sick people a space module, and how the lack of gravity affects the process of taking blood and ing a nasal tube. Dr. Watson does her best, but her colleagues die off one by one and the people at NASA don't want to risk bringing the platform back to earth. Only Emma's husband, doctor/astronaut himself, refuses to give up on her. As we read along, eyes popping out of our heads, all that's missing is one of bland NASA voices saying, "Houston, we have a problem -- we're being attacked by tiny little creatures that are part human, part frog, and part mouse."
