Nice finds! I've read 12 Rules for Life and Ender's Game (audiobook). Ender's Game was so good, I listened to it several years after having seen the movie so the ending was a little bit spoiled but still enjoyed it thoroughly.
Have you read I, Robot? I wonder how good that one is.
I've not read I Robot. The only Asimov I've read is the first couple of foundation books. They're excellent. I have the rest of them. I havent touched them lol.
