Letters from Bear — Gauthier David

Bear can't imagine a whole winter without her friend, so when Bird migrates south, Bear decides to follow. She's never left the forest before, but that won't stop her from crossing oceans and mountains -- and sending letters along the way. But a surprise is waiting for Bear on the beach… 

Richly told in amusing letters and lush illustrations, this adventurous story invites readers to consider just how far they'd go for their friends.
