Undead

Undead by Cirsty McKay stars Bobby who finds herself in danger when her classmates turn into rabid zombies on a ski trip.  Bobby, Smitty and a few other classmates find themselves on the run from their teachers and classmates who were turned into zombies.  They have to get away and find out what it was that caused the mass outbreak.

This is a terrific humorous horror novel.  It did a perfect job of combining the absurd with the horrific keeping the reader both scared and giggling throughout.  The side characters are caricatures and so much so that it's funny.  The nerdy computer guy, the bitchy cheerleader, the outcast, rebel and of course the evil villains and terrifying zombies. 

Appropriateness:  This book has a lot of zombie violence.  Vice principals are beheaded, little kids are bitten and the main characters are in a lot of danger.  Aside from the violence there is no adult content.  The romance was a very small subplot and was limited to just kissing.  I would recommend this book to readers 12+
