for Iris and Walter by Elissa Haden Guest and Christine Davenier
Iris is sure that life in her new home will be just awful. There is nothing to do and no one to play with in the country. Iris will never be happy there. Then Grandpa suggests a walk. Down the road and around the bend, they discover a huge green tree, a secret hideaway--and a boy named Walter. Maybe life far from the city won't be so lonely after all.
