Gr 2-5-This slight graphic novel features kid-friendly cartoon drawings. It starts off on an "ordinary night in Widow's Peak, Nebraska," when Jeremy Kreep's little brother puts a tooth under his pillow for the tooth fairy. Instead of finding a dollar the next morning, he finds a puddle of green slime, and Jeremy and his friend Nessy set out to find the source of the mysterious substance. They can't get the police to take them seriously as the officers are too busy searching for the Horrible Hound from Heck (Heck, NE, that is). The adults in the story are a bit bumbling, but the kids save the day by finding out the truth behind the slime and the Horrible Hound. The back matter contains a useful glossary, "Some Tooth Truth" (interesting facts about teeth), discussion questions, writing prompts, and Internet sites.-Nancy Kunz, Tuckahoe Public Library, NY (c) Copyright 2010.
