A while ago - it was called 'Indistinguishable From Magic'. Would've been nice if they had told the author
Don't we already have those? Dark Mirror, Dark Passions, DC's Mirror Universe Saga, IDW's Mirror Images, Marvel's Mirror, Mirror one-shot, etc. -- all different versions of the MU.
^ Yeah, but we didn't have to stop there.... I mean, there's no reason there can't be more stories set in those alt-MU's, is there? This would simply be a collection of those. And how's this for a Myriad collection: Actual complete stories set in some of those alternate universes from Q & A. (One of those WAS an alt-Mirror universe, in fact.)
I don't suppose Pocket could convince anyone that To Seek a Newer World, Refugees, Greater Than Death and The Hazard of Concealing are actually all set in some other timeline than the last movie, and release them as Myriad Universes books? Use find and replace to befuddle the lawyers! Kirk thought back to his recent battle with <Reno>, the fearsome <Klingon> from the future who had used <McCoy> Prime's <Mauve> Matter to destroy <Andoria>...
Nah, that doesn't sound plausible enough... Kirk thought back to his recent battle with <Reno>, the fearsome <Andorian> from the future who had used <Sotty> Prime's <Mauve> Matter to destroy <Babel>... Add in some Andorian reproduction crisis stuff and you'll be set.
Why "Star Trek: Mad Libs" hasn't come out yet in all these years, I have no idea (other than license, of course)
