This book was an okay (and fast) read, though not for the faint of stomach. The premise, here, is that a zombie virus has decimated about 2/3 of the population. Three scientists, working on an island, are trying to find a cure for the virus and are using the method of autopsy to discover how the virus ticks. Of course, the scientists - at the point of read - are all zombies, themselves, or have disappeared; all that is left is their notebook. Luckily, one of the scientists was a graphic medical artist who just happened to have time (and pencils) to detail the internal workings of a zombie. Yup, a little cheesey. The work is provocative, though, if you are interested in the science of how a virus works. It does require a little biological knowledge on the reader's part, which requires good attention - at some parts. In that sense, it does read like a medical text. What I didn't like about this work is that the zombie virus, here, is airborne. So, really, there is absolutely no defense against it. You can get it from being bitten, which causes you to transform quickly, or you can get it through air exposure (like a cough) and it will simply take you longer to transform - while you, of course, infect hundreds of others. For me, humanity has to have a basic form of defense against the zobmie plague if there is to be any fun. Otherwise, it's just depressing as you just sit (read) around waiting for the last man on Earth to turn. Not bad, though, if you've got an hour to spare.
