No need to go rushing out to buy this one, it's not available any more. I found it in a second hand bookshop and bought it because I've enjoyed Asimov's previous work.
This is a collection of 5 short stories (Nightfall, Green Patches, Hostess, Breeds There a Man...?, C-Chute) written in the 1940'/1950's and originally published in Science Fiction journals of the time, re-published in a collection in 1970. Over 60 years later and these stories are still a joy to read. I want to tell you what the stories are about, but to do that would spoil them.
If ever I create Rootie Ratings(tm), this book will get top marks 5 times over (once for each story, they are all superb).
