Section 31, an amoral, rogue division of Starfleet, manages to affect the starship Voyager, lost on the other side of the galaxy. Seven, a new and trusted crewmember rescued from the Borg, is being targeted with a series of incidents. The crew, whom Janeway thought she trusted implicitly, is harboring a traitor.
Pocket Books editor Marco Palmieri explains, "The challenge was in coming up with a plausible Section 31 scenario for Voyager, given its distance from the Federation. We hit upon the idea that an agent had been imbedded on the ship specifically for Voyager's mission to the Badlands, because of the escalating threat to Federation security posed by the Maquis. The twist was establishing that she was already deceased by the time Shadow takes place (the nameless blond officer in "Scientific Method" who dropped dead on the bridge), but that action she'd taken prior to her demise had just begun wreaking havoc on Voyager."
