Unlike many series, this one keeps the readers' attention even after the third or fourth book. The length (barely over 200 pages) combined with plentiful illustrations and fast-paced narrative, makes this a book that doesn't take too long to finish. Combine that with the appeal of zombies, and this is a winner. While it is gory enough to please the most brain-hungry thirteen year old, it's goofy enough to not give younger readers nightmares.
This is the perfect book to hand to a child who has just been told that The Walking Dead is not a show that is appropriate!
