The Mirror Universe Reading List is centered around the series of novels fleshing out the history of the mirror universe, specifically Emperor Spock's Memory Omega movement. In addition to the main novel line, one short story is also connected, from Seven Deadly Sins.
Eight other Lit-verse linked novels and comics are also connected to the mirror universe in various ways, and are included here: Discovery: Die Standing, Stargazer: Three, Deep Space Nine: Warpath, Deep Space Nine: Fearful Symmetry, Deep Space Nine: The Soul Key, New Frontier: Turnaround, Section 31: Disavowed, and Coda: Oblivion's Gate.
Dark blue denotes the primary narrative. Read these for the bare bones story. Light blue denotes the expanded storyline. Read any or all of these to go a bit deeper. White denotes every other connected story, regardless of overall continuity. For the absolute simplest story, read the essential duology.
Hover for notes. As always, not every
reference to every other story is mentioned, just the one I chose as
most important to show the expanding Lit-verse web.
