I know the description above probably might seem a little cliched, and the stuff of paperback reviews, but I really did find the stories excellent, particularly 'Goodbye Columbus'. The only problem I could see was that some aspects of its sexual politics might need to be explained to people who didn't grow up in 1940s and '50s America... Nevertheless, the story's sharpness and originality have stood the test of time and it still carries a real sting, and some psychological truths, over 40 years later.
The other stories are also insightful and engrossing and well worth reading.
I'd recommend the book to anyone.
