I had to watch Trials and Tribble-ations
after finishing the book and the author expanded the characters in a very believable fashion.
My only (slight) criticism? I think Dulmur's origin story should have been saved for another book. It's an interesting story that felt a bit rushed, if only because there was so much material that needed to be covered.
The ending? Brilliant. Asimov would have been very proud.
concept could easily be made into a book series...I hope that happens. It would be great to see other authors' take on the expanded concept.
