Book excerpt: Clever ghosts-in-training solve a scary haunted house problem. Groana, Moana, and Shrieky are three little ghosties learning the tricks to giving a good scare. They stomp around, spook family pets, and slam toilet seats. They're all set to pass their Halloween test, until they find a family that doesn't scare easily. In fact, they LOVE everything the ghosties send their way—especially the bats and rats! What does it take to horrify a household like this one? Sometimes you have to think outside the box (or casket!) to find a way around a problem.
