A psychopathic killer stalks the corridors of space station Deep Space Nine, brutally murdering its inhabitants. Catching him is complicated by the fact that he is able to assume any shape, inanimate or living. This is the first original novel based on the popular TV show, Star Trek: Deep Space Nine. Combining the elements of a good murder mystery with the Star Trek universe, the author has produced a gritty, well-written novel.

Deep Space Nine is forced to curtail entry to the wormhole due to increased graviton emissions, and an air of biting tension settles over the station. This anxiety leads to the murder of an Edeman religious leader, Commander Benjamin Sisko and Security Chief Odo realize they face a larger problem.

Soon Sisko and Odo have more lifeless bodies on their hands and a killer who strikes without motive. Then, both the Edemans and Cardassians arrive threatening to destroy the station unless the murderer is given to them for retribution. In order to save Deep Space Nine and stop the killing, Odo must try to destroy a powerful assassin who is the only link to his mysterious past.
