TJ Trapper is just an ordinary fourth grader until the new girl, Livvy Armstrong, joins the class. Then trouble starts! Livvy is a bully. She calls kids names, starts rumors, and tries to talk kids out of going to TJ's birthday party. TJ doesn't know what to do, but he knows he doesn't like being bullied. Once he talks to his dad and Auntie Stella, TJ gets some tips on how to stop a bully. He learns about reporting and being an upstander. Soon, TJ is more than just an ordinary kid--he's TJ Trapper, Bully Zapper. Aligned to Common Core Standards and correlated to state standards. Calico is an imprint of Magic Wagon, a division of ABDO.
