In the year 2050, the United States sends the FBI to govern its space station, the Empyrean. Under the command of former fighter pilot and FBI field agent Samuel Lord, the space-based "Zero-G" men are in charge of investigating terrorism, crime, corruption, and espionage beyond the Earth's atmosphere and of keeping an eye on the rival Chinese and Russian stations.

During the Zero-G team's first days in space, a mysterious and beautiful scientist, Dr. May, shows up to the Empyrean claiming that important research has been stolen from her lab on the moon. Her arrival suspiciously coincides with timing of a tsunami that destroys part of the coast of Japan, and her unusual behavior makes Director Lord think that Dr. May might know more about the disaster than she's letting on. Meanwhile, the Chinese space station has gone mysteriously silent.

In this "tightly paced blend of police procedural, military SF, and space opera, set in an intriguing near-future world" (Publishers Weekly), Director Lord must connect the dots to discover who or what has caused the tsunami as well as subsequent disasters, and how Dr. May and the Chinese might be involved.
