Book excerpt: As a demigod, Maui has done a lot to help humanity. He slowed the sun to make the days longer and used his magical fishhook to pull up new islands. He battled monsters and even helped create coconuts. But there's one thing Maui has never done: be somebody's friend. Follow Maui on his journey to become the best friend ever--with some help from the brave voyager named Moana, that is.
