I picked this up while I was browsing books at the library. The minute I opened it I was sucked in and ended up spending most of the afternoon at the library reading this book. Even if you're not really into viral pathology I will still say to give this book a try. It reads more like a mixture of horror story, history and anthropology lesson. The authors give an astonding amount of insight to how this virus (and other sickness like it) can be traced through out human history, and how it helped shape us in many ways we never realized.I read this for research, but I plan to buy it because it is one of the best non-fiction books I have ever read.
