A very interesting concept to how we could have actual zombies.
An easy plot to follow, tho at times, found it very hard to "relate" to the main character's motives for needing to do what he just "had" to do.
The book ends abruptly so as to leave possibilities for the next book, it
did leave it at a great place to pick up from in the next book.
I downloaded this book from amazon kindle for free.
