Imagine this. You're strolling through whatever the zombie equivalent of a "park on a nice day" is, having a good, reasonable, zombie-filled time, when you round a corner, and there's a horrific scene playing in front of you. And I mean horrific to someone who's become accustomed to zombies. That's how this book plays out. It's a joyful zombie experience for about two thirds of the book, and then you're slapped in the face with all the scary bad things. And Darren Shan does it all delightfully.
