I assure you that once you pick up this book you will not want to put it down.It's slim but over-sized with captivating close-up photography on almost every human organ you can think of accompanied by terse explanatory text. This book sure does justice to the saying "A picture can say more than a thousand words". It has the kind of photographs you might not see anywhere else. I loved the fact that it also lists major medical discoveries and some very good websites to explore.
