Star Trek: Mission’s End
The most important “lost” tale of the Star Trek saga can now be told: The final mission of the original Starship Enterprise and her crew. What prompts Mr. Spock and Doctor McCoy to retire from Starfleet? What earns Kirk his promotion to Admiral? And what is the mystery of Archenar-IV that threatens to tear the Federation itself apart? All will be revealed!
It says it’s the final mission, but i’m pretty sure we’ve seen a few other “final missions” for the TOS crew. I did enjoy this story, it has some real classic science fiction elements to it, with an abandoned planetship being run by a society of giant spiders.
One unrelated note, I bought this at a convention in a “whole story pack” where they sell you the entire series of single issues in one bundle, which you can’t open to inspect. I got issues 1-4 of the series, only to find out that there was one more missing issue. I was able to read it online, but man that sorta steamed me a little bit.
