Whaley
What happens when you have the best friend in the world, but no one believes you that he exists?  Max had such a friend, he was a whale, and Max called him Whaley.
They played and talked for hours about what it's like to be a whale and what it's like to be a kid. But when Max told his family about Whaley, no one believed him, not even his great-grandmother. Why? Because in the island where they live, in the northernmost corner of the world, they've never seen a whale.
This book illustrates what happens to a child when adults don't believe in him and dismiss his words as insignificant. It also tells a story of self-belief, even when everyone around you is saying you're wrong.
