Thanks for the list. Nice to see some old friends on there. My all time favorite is Heinlein's The Moon is a Harsh Mistress. I think it is his best. First time

Thanks for the list. Nice to see some old friends on there. My all time favorite is Heinlein's The Moon is a Harsh Mistress. I think it is his best. First time I read it I was in the sixth grade. That was 45 years ago. I've read it many times since, and will no doubt read it again.
