This started out as a comment, but it got long, and I decided to move it here. So, thank you,
aspidites, for prompting this!
Diane Duane wrote quite a few
Star Trek novels, though I always hope that she will write more! Well, I always hope she'll write more
anything, frankly. Fortunately for me, she does.
The Wounded Sky was lent to me almost twenty-five years ago by a fellow Trekker, for a cross-country trip. I read it so much that I bought her a new copy when I returned.
My Enemy, My Ally is the start of her take on the Rihannsu/Romulans; TNG eventually took them in a different direction, but many hold Ms. Duane’s vision to be better. This and
The Wounded Sky can be read individually.
Spock’s World* was, IIRC, the first Trek novel to be published first in hardcover, and is a history of Vulcan intertwined with a present-day adventure for the crew. This should be read, if for no other reason, to see Doctor McCoy debate the entire planetary population of Vulcan. *snerk*
The Romulan Way is sort of the other half of the
Spock’s World story, though they can also be read separately.
Doctor’s Orders centers on McCoy and is tremendous fun--to my mind she writes the characters as they
should be (but aren’t always, even on screen), and her treatment of Bones is quite possibly the best out there.
Swordhunt and
Honor Blade are really two halves of one book that I suspect Pocket made her slice in two; they pick up the Rihannsu story and shouldn’t be read alone.
The Empty Chair is nice and thick and finishes that story.
The Bloodwing Voyages and
Sand and Stars are “collection” volumes, not original stuff.
For TNG she did
Intellivore, and
Dark Mirror, which is TNG and the
Mirror, Mirror universe.
She also wrote stories in various Star Trek graphic novels and manga, and co-authored the TNG ep
Where No One Has Gone Before, though she points out
here that it bears little resemblance to the original script.
Some were co-authored with Peter Morwood. Like all her works, these are rich with tributes, hat-tips, sly guest appearances, and inside jokes that still have me laughing after a quarter of a century of re-re-re-reading. Remember, don't judge by the covers, and for more information check out
her site. She's done many other
gorgeous books.
* The audiobook was read by George Takei, and is, I believe, abridged (alas). I tried to listen to it but broke down in uncontrollable laughter when hearing Mr. Takei do the Rec Deck computer. His voicing of Kirk is just a bit too sly as well, not that I really blame him...it was done quite some time ago!
