Those interested in reading this book must be warned that it is a rather hefty tome in both size and breadth and therefore should be nibbled on over a period of days or weeks. This is not to say I did not enjoy the book, I did, it is just not one that I feel should be consumed in multiple sittings all in a row. It is most definitely a short history of the world, how the Earth came to be and eventually how humans came to be and everything in between. As Bryson himself is not a scientist he approached it in a manner which non-science oriented people would be able to enjoy I believe, at least if they go into it with genuine curiosity. The world truly is fascinating. I do have a scientific background and degree so the book did not contain much information I had not already acquired at some point but it was still enjoyable and I recommend it.
