Iris and Walter will join Frog and Toad, Henry, and Manji in the easy reading category.

After a move, Iris is sure that life in the countryside will be terrible. There's nothing to do and no one to play with her. Iris will never be happy there. Then Grandpa suggests a walk. Along the way and around the bend, they discover a huge green tree, a secret hideout - and a boy named Walter. Maybe life away from the city won't be so lonely after all.

In Iris and Walter's favorite books, together the two heroes discover that anything - from adjusting to a new home to the first day at school - is easier when you have a best friend to help you.
