The Hamster of the Baskervilles — Bruce Hale

Elementary school is a wild place. But this is ridiculous, even for Emerson Hicky.

Trashed classrooms. Gnawed walls. Tunnels riddling the playground like worm chunks in a pan of earthworm lasagna. Something wild is at work at Emerson Hicky.

Chet Gecko doesn't believe in the supernatural. His idea of voodoo is a bowl of his mom's cockroach-ripple ice cream. But when a teacher reports seeing a monster by the light of a full moon, Chet and Natalie take the case.

But will they survive long enough to answer that age-old question: If it doesn't act super and it doesn't look natural, why do they call it supernatural?
