"Surprisingly good"
I thought this would be an odd mixture with Kirk, Picard, and Janeway but it actually worked rather well. Unfortunately, I was not aware until I started listening that this is the third book in a trilogy. It's preceded by Captain's Peril and Captain's Blood (which oddly Audible does not have). Too bad Audible does not make this clear. Not having read the previous two books some things did not make as much sense (like how McCoy and Scotty got to the future), but the story appears to only loosely depend on the events in the other books.
