Just finished "The Grand Design" by Stephen Hawking and Leonard Mlodinow. Have to say, I was not that impressed. I read "A Brief History of Time" and a re-read in "A Briefer History of Time" and felt much of the time the reading of "The Grand Design" was like reading the same material for the third time. Then, in the end I found the conclusions less perfect than I had anticipated from the author. His next book will have to have some really good critics for me to buy it.
