I bought this from worldofbooksusa and I am so happy with this book. I paid less than 50% of the price for a brand new copy, but this book looks like I bought it off the shelf of Barnes and Nobel. There are no ripped or curled pages, the DJ is in mint condition with no creases, wrinkles or tears, there is no writing on any of the pages.This book is big! 506 pages, oversized, small print. And the author is Richard Dawkins. What more could you ask for? This isn’t a book you can read like a novel. It’s more like a text book if you were taking a course, and I do find myself reading parts over until I fully comprehend. However, if you are remotely interested in evolution, genetics, biology - even physics, this book will keep you happily engaged, totally interested, and absolutely fascinated with its content. Definitely not a book I would loan to ANYONE!
