Re: Best Novels, Comics, etc. Set Between TOS Season 3 and ST:TMP?
"Traitor Winds", part of the four book "lost years" (all of which are in that timeframe) is superb. I read it before the preceding books, you don't really lose much by reading it first if you so choose. The other three are ok but nothing special.
In defeat, malice. In victory, revenge.
