Here are the links to my unpublished Star Trek prose short story:
Part 1, Parts 2 & 3, Part 4, Part 5, Part 6, Parts 7 & 8, Part 9, and Part 10.
I think I nailed the voices of the characters, but I can see why they didn't pick it up. My original story was pretty much as Chekov describes it in part four, but it seemed generic and familiar. It was probably more marketable but I decided to do a "hang out" piece that emphasized character and continuity. It's really a love letter to the characters (especially McCoy). If you are a fan of this crew, I hope you enjoy it, because it's for you.
