Star Trek: Vanguard: Reap the Whirlwind
It’s the third book in a nine book series, but it feels like everything gets nice and neatly wrapped up. I’ve already started the next book, so I know that things aren’t as neat as you might expect, but if you were to read the first three books of this series, you’d get a pretty damn good Trek trilogy that really moves. Of particular note is that these books do a lot to fill in the background of the Tholians, which I think only appear on screen a few times in the Trek TV series, but have been featured pretty heavily in the comics lately, and it’s great to see such an alien race get the history that they deserve.
