A collection of three interconnected novellas set in the far future on a pair of binary worlds. The first about young man coming of age and learning his heredity, the second a story purportedly told to an anthropologist by aboriginals, and the third a set of documents about an expedition and the imprisonment of the same anthropologist. I enjoyed reading this but can’t say I really understood it, which means, as usual with Wolfe, I need to reread it.
