The book is, Tracking The Man-Beasts: Sasquatch, Vampires, Zombies, And More by Joe Nickell.
I will start by stating that Joe Nickell is a dedicated debunker. He doesn't buy into pretty much anything. This said this doesn't mean that one should pass this book by. The book, Tracking The Man-Beasts has a lot of good information covering everything from bigfoot to werewolves, zombies, aliens, demons, and yes, vampires. So if you can overlook the author being a dedicated debunker then you can find enjoyment in the information provided. The only problem I have with the book is that Nickell doesn't quite understand when something is told in a "nod & wink", versus something that might actually be a reality. Nickell simply puts everything in the same category and dismisses it. This inability to distinguish between such highly annoys me.
On a scale of 1 to 10, with 1 being the lowest and 10 being the highest, I give the book a 6.
