The end of a universe
All of the Star Trek novels that take place in the 24th century have been part of a shared, consistent universe for the last 20 years. These novels take place after Nemesis, after “What You Leave Behind,” and after “Endgame.” They fall into the novel series The Next Generation, Titan, Deep Space Nine, Voyager, and various crossover miniseries.
As has happened in other universes, this one is coming to an end — the Coda trilogy forms the conclusion. Subsequent novels, at least for now, will take place during the series — such as TNG: Shadows Have Offended. The TOS and Enterprise lines of books shouldn’t be affected, but we’ll see.
