Tillie and the Wall
Leo Lionni (1991), Knopf
Tillie is a curious little mouse. For as long as she (or anyone!) can remember, a long, long wall has separated them from the rest of the world. Tillie explores and experiments until she finds a way to get to the other side – where she meets more mice! After a celebration, she leads them on an expedition back to her side where everyone parties together to commemorate Tilly’s adventures and discovery.
