From the award-winning author of the Coyote series comes a tale of mystery and adventure at the far reaches of the solar system. In the early years of the 22nd century, an international space expedition is exploring the moons of Jupiter. Tragedy strikes when a bathyscaphe lowered into the global ocean beneath Europa's frozen surface is lost, costing the lives of two scientists. The lone survivor: the bathyscaphe's pilot, a woman whose haunting beauty and sexual hunger led both men to have affairs with her. She claims that her craft was attacked by an enormous creature prowling the frigid waters beneath the ice. Other expedition members doubt her story. They believe the creature doesn t exist, and that she's lying in order to hide the fact that she deliberately killed her former lovers. It's up to another crewman the survivor of a freak accident aboard the expedition ship to determine the truth. Is this murder...or one of the greatest discoveries of all time?
