The Theory of Everything: The Origin and Fate of the Univers . It has come to our attention that the book "The Theory of Everything: The Origin and Fate of the Universe" has been published. Professor Hawking would like to make it clear that he has not endorsed this book. The text was written by him many years ago, however the material has already been published in books such as 'A Brief History of Time'. A complaint was made to the Federal Trade Commission in the US in the hope that they would prevent the publication. We would urge you not to purchase this book in the belief that Professor Hawking was involved in its creation.

Shocked. Stunned. Horrified. . I realize that Patterson is known for his exciting, page-turning reads. I realize that he is famous for the relentless pace of his novels. And, most importantly, I realize that he is famous for stunning twists at the endings of lots of his books. Keeping all that in mind, I have to say that I was shocked and hurt by the, well, absolutely horrifying surprise ending to this book. To say it came at me out of left field would be a massive understatement. It's more like I was standing at home plate in Dodger stadium and was hit by a ball thrown from left field in Yankee Stadium. Truthfully, I never saw it coming. And I was horrified by it. I finished the last pages with my mouth hanging open. And I feel betrayed as well. I realize that twist endings happen often, especially when it comes to Patterson, but I DID NOT LIKE this one. I felt hurt by it. Putting that aside, it was a good read overall, which is why I give it 2 stars instead of one
NEG

Too advanced for beginners! . I found this book impossible to use! The photos and illustrations were so detailed, with lines traveling everywhere, that I couldn't transfer what I saw on the page to what I saw on my hand. I was disappointed
