Template:Realworld Star Trek: Mirror Universe is a three-book series published by Pocket Books. The first two comprises collections of three novels, the last a 'flip book' style story.
The novels are based on the mirror universe episodes of Star Trek: The Original Series, Star Trek: Deep Space Nine and Star Trek: Enterprise, which all have novels dedicated to them. Star Trek: The Next Generation, Star Trek: Voyager and Star Trek: New Frontier stories are also included.
The DS9 novel "Fearful Symmetry" is part of this series, as well as being the latest edition of the novel series set after "What You Leave Behind". The Deep Space Nine segment "Saturn's Children" will also bridge the gap between "The Emperor's New Cloak" and "Warpath".
