I seldom find the time to do anything these days...let alone write a review...but I fell that this time, it is a necessity. Hazen has crafted a beautiful, intricate and compelling summary of the history of the Earth (certainly, 4.5 billion years is no easy task). Without going into too much detail, without patronising the reader with obvious information, written in a style that is easily enjoyable, this book is a gem. Hazen is up there with the rest of them, i.e. Sagan, Fortey, Dawkins, Lane, Benton, etc. in bringing the beauty and fascination of science in an accessible format. I can assure you, if you have an interest in science, you won't be able to put this book down. Well done!
