On the eve of a high-stakes diplomatic summit, Deep Space 9 is thrown into chaos by a sudden communications blackout and a string of deeply unsettling incidents. With senior leadership called away, Worf, Dax, Odo, and Bashir must hold the station together as tensions rise among visiting dignitaries.

Then, a distressed starship arrives with explosive claims—and one member of the DS9 crew stands accused of murder. As suspicion spreads and paranoia takes hold, a creeping sense of dread settles over the Promenade. And somewhere inside the station’s holosuites, something has gone terrifyingly wrong…

A locked-station thriller begins here.
