Query: Quite literally life changing.

Most of the previous reviewers have pretty much nailed the book right on the head: it is a fantastic and graphic novel on true events surround Ebola and Marburg. It is written in such a way that even the novice reader could follow, though there are a lot of scientific terminology that may require some googling.For me personally: this book has literally changed my life.
