Now I'm onto 'The Jewels of Aptor' by Samuel R Delany. It was written in 1961 and as well as being the author's first novel it is also the first book of his I've read.
It initially sounds like a fantasy adventure story, being about basically a jewel quest to appease a high priestess but is apparently set after a nuclear holocaust.
Well I found this book OK once the characters and the mission had been established. Some interesting post~apocalypse ideas here but I found the writing a bit odd in places. I wasnt sure if it were typos or idiosyncracies of Delany's style. Apparently thats typical of Delany and things only get stranger.
An OK book, but not really a keeper.
