Probably not the best, but I enjoyed the novelization of Star Trek IV. You get to actually see what the probe is thinking from its point of view, which was fun and super interesting.
Vonda N McIntyre is one of the strongest Star Trek writers of that era.
She was very successful in writing her own original science fiction novels and short stories. She was a collaborator of Ursula LeGuin and a leader in a group of writers in the Northwest.
