Star Trek: The Lost Years

I enjoyed it. It's largely a McCoy and Spock story that takes place presumably a few months or years before Star Trek: The Motion picture. Theres a sense of tension between the TOS characters that leads into that film; we even get an explanation for McCoy's goofy beard in the motion picture. James Doohan gives a solid performance here, as does Leonard Nimoy in the few chapters that he narrates. I don't really have any major complaints about this book. Every major plot point is set up well in advance, and it doesn't conflict with anything established in TOS or Star Trek 1-6. Its pretty good.
