Jim, a friend of mine passed on an extra copy of this that he had to me a few years ago which I've never read. In fact, the only book of Bishop's I have read is No Enemy But Time - similar vein?
They share an anthropological core but I'd say they're pretty different.
Transfigurations is set on an alien world and deals with the study of a group of alien hominids called the Asadi. It's an expanded version of a Hugo and Nebula-nominated novella titled
Death and Designation Among the Asadi, which forms the first part of the novel. I don't want to say much about the actual story because the less you know, the better. It's an earlier Bishop book than
No Enemy But Time but they reflect similar interests in the part of the author.
I hope that's helpful.
I obviously recommend it!
Jim
