Star Trek: The Q Continuum is a Star Trek novel trilogy written by Greg Cox and published by Pocket Books, a division of Simon & Schuster Inc. The three books, Q-Space, Q-Zone and Q-Strike, tell the early history of Q himself, and lead up to an ultimate confrontation between himself, the Enterprise, and another omnipotent being from Q's "childhood", which may lead to the destruction of the galaxy.
The USS Enterprise (NCC-1701-E), staffed by its usual crew (except for Worf, who is on DS9), is on a mission from Starfleet Command, to assist Lem Faal, a Betazoid scientist, in breaching the barrier which encircles the Milky Way Galaxy. Along the way, Q interrupts them, warning Captain Picard to abandon his mission, with the usual warning of impending doom but no explanation.
Along the way, Q introduces his wife (as seen in the Voyager episode "The Q and the Grey"), and newborn son, q (seen at the end of that same episode), who for the most part remain on board the Enterprise during the story, assisting them at times only when it suits Mrs. Q. The Enterprise is attacked by the , a species of gaseous creatures it had encountered before ("Déjà Q", season three of Star Trek: The Next Generation). Q takes the opportunity to remove Picard from the Enterprise, taking him with him on a journey back through time and space to his own early childhood.
Q shows Picard his history (including how Q created the Nexus, and an experiment which resulted in Q's invention of antimatter), and eventual meeting with another omnipotent being called ("Zero"), who Q eventually helps escape from his frozen prison planet in another plane of the multiverse.
