I initially bought this book because I'd seen a news article about it containing images never before seen using the latest in scanning technology (e.g., neural development in a foetus).
The images are absolutely stunning - they cover a variety of cell types, parts of the body, development of a foetus, bacteria etc. My favourite is a close-up of a toothbrush against the surface of a tooth - you'll never look at such mundane things in the same way ever again!
I'd recommend this book to anyone who has an interest in the human body - there is little text, which is great since the images more than speak for themselves. It's a great coffee table book as well as a book which you can dip into at any point.
