"Equinox" was a two part episode of Star Trek: Voyager, comprised of the 118th and 119th episodes overall in the series, aired as a cliffhanger 26th episode of the show's fifth season, first aired on 26 May 1999, and continued in the sixth season premiere on 22 September 1999. The episode was written by Rick Berman, Brannon Braga & Joe Menosky and directed by Alexander Singer. A novelization written by Diane Carey was published in October 1999.


Captain Janeway believed she commanded the only Starfleet vessel in the Delta Quadrant—until the USS Voyager came to the rescue of the USS Equinox, a battered starship besieged by a revenging horde of extra-dimensional predators.

Helmed by Captain Rudolph Ransom, the Equinox has been trapped in the Delta Quadrant even longer than the Voyager and the ship and crew show the scars of a constant struggle to survive. But Ransom and his people are hiding something as well: a shocking secret that will ultimately pit captain against captain, starship against starship, in an explosive conflict that may cost Voyager the life of her captain!

A powerful novel based on the thrilling two-part television adventure!
