Students often fail to listen to announcements, but put "zombie apocalypse" on, and 25 boys will come asking for the book! I was very leery of this book for middle schoolers, because the illustrations make it look as if it falls on the elementary side of the Pilkey Line, but it doesn't. My boys want scary zombie books like Z or The Enemy, and have to be convinced to stick with The Vampire's Photograph, but this will work. Zack, Rice and Madison are having a nice birthday celebration when things start to go wrong. Zack's sister Zoe becomes a zombie, and pretty soon most of their town is lurching along, looking for brains to eat. Most of the action concerns escaping the zombies, whether by jumping down a clothes chute into dirty underwear or trying to drive a car. The three try a couple of antidote to try to stop the infection, but they are back in Undead Ahead and the soon-to-be-released Sludgement Day.
Strengths: There's plenty of gross-out humor and zombie descriptions, but I don't agree with the reviews that think this is funny.
Weaknesses: Twinkles. Really? Turn a cute little dog into a zombie? I was rubbing Sylvie's tummy and she did not approve!
