Finished reading the three bantam books that Christopher recommended.
I enjoyed both Planet of Judgment & World Without End, especially the prep that any sane person would do before exploring the unknown. Found it interesting that both Haldeman's books had the ent crew going for a sort of "one way trip". I felt World Without End had the more compelling aliens and was more fun in general.
Spock Must Die! I found rather odd when it came to the mechanism for the main draw in the novel, what happened to spock. Other then that I quite liked it, the length & nature of the self imposed mission was fun, as was the eventual ending, as a kind of what if.
