The Big Nap: A Chet Gecko Mystery – A Hilarious Chapter Book About a Reptile Detective Solving a School Zombie Mystery for Kids (Ages 8-12)

Grammar school--it's all about eating and sleeping. Well, for Chet Gecko, anyway.
To Chet, nothing is more divine than a plate of Mrs. Bagoong's Mothloaf Surprise followed by a sweet bit of shut-eye on the playground. (Besides a few Pillbug Crunch bars and a monthlong holiday, that is.)
In these two hilarious mysteries from Chet's tattered casebook, he and his mockingbird partner, Natalie Attired, must catch a cafeteria thief, foil the sinister plans of a weaselly zombie master . . . and still take part in the Nations of the World PTA assembly. (Fourth-grade detectives get no respect.)
