Never Make a Giant Mad: Book 2 (Paperback) (ISBN-13: 9781728462912)

Felix's favorite toy, a robot dog, is lost in the land of the trolls. With a little help from an all-seeing troll witch, Felix and Calcite get close to finding it. That's when they learn a big problem is standing in their way: Garganto, a giant who guards the path ahead. Garganto says no one gets through his gorge--even if Felix's toy is on the other side. But he's never met a duo like Felix and Calcite!
