Set directly after “The Naked Now”, the Enterprise decides to use their extra three days to do a low-stakes check on an away team on a boring planet. Suddenly, everything goes wrong! The first book in a trilogy, so nothing gets wrapped up here, but it’s the usual Trek adventures. Some extra points for having cave exploration scenes that were claustrophobic enough to wig me out a little. 

Weirdly, the summary blurb on the back of the book (and thus, on this site) is entirely unrelated to the actual plot.
