Armed with a pencil in her ponytail, a pot-bellied pig, and a pocketful of gummy turtles, there's nothing that fourth-grade artist Channing O'Banning can't do. When Channing discovers that her best friend has gone crazy over the new boy at school, she fears that she's lost her best friend forever. Drawing her frustrations out in her secret sketchbook, Channing is determined to make Marco, "the best friend thief," her worst enemy. But when they both wind up in the rainforest of Costa Rica, Channing soon discovers that Marco may be her only hope for survival. From zip-lining through the jungle and daydreaming of monster frogs to finding out what it means to "go green," Channing not only discovers the wonders of the rainforest but learns a little about herself and the value of trusting others. With art education often being taken out of the classroom, parents and teachers - as well as readers who like to draw their way through one adventure after the other - will be excited that Channing O'Banning has come to the rescue.
