The much-honored illustrator continues his exploration of reconciliation with another fable. Too high to climb over, too long to journey around, the wall has long been taken for granted and ignored by the mice who live beside it--except for Tillie. For her, it is the source of imaginative speculation: What fantastic beings live on the other side? But even with the help of her friends, she is unable to find a way to the other side--until the sight of a tunneling worm suggests a new approach. And once she gets over there? Ordinary, friendly mice, just like herself. Lionni's collages of patterned and textured papers on a clean white ground are always well designed and attractive. Bold and colorful, these are perfect for sharing with a group.
