First off, I love the art in this book. The story line is questionable to me. A set of Cranes have lost their baby chick. They send a note to the postman to help find the chick. Polar Bear talks to all his friends, and all those on his route to help find the chick. A few weeks/months later Polar Bear gets another postcard from a different set of Cranes saying they found a chick and raised it, but now need to find the parents. I guess what I don't like is the spring and summer time lag. Why wouldn’t these cranes from district 3 notify him sooner that they had a chick. I can see a day or two, but not enough days that the chick is grown and about to fly. I love, love, love the art, but I do not like the message in the book.
