Query: This book sould get 6 stars

I really liked this book, mainly because: a) it is interesting b) it is original c) it is not written in a style that makes it as tedious and boring as most books you were assigned to read in high schoolAsimov had also written some novels about robot which are also very good and tie into the his Foundation series (also very good)I recomend that you read this book, and just about every other book he has written (I say just about because I have not read them all, only the ones I have seen in bookstores and my library) They are all quite good and have been written by a very skilled author
