The Book of Blood is absolutely fascinating!  I was mesmerized reading it.  It includes so much information about blood–who knew?  There is the elements of blood, the lost science of Egypt, disease, transfusions and bloodletting, terms ‘blue blood’ and ‘cold blooded’ explained as well as others, blood pressure and pulse, the early science of ‘seeing’ blood, and more.  The info is delivered short and sweet, with just enough to pique curiosity and not too much to get bored or tired of it.  Whether you read it cover to cover, or in bits and pieces,The Book of Blood should be in every school library.
