MARY LIVED IN A BIG HOUSE with a very little mouse. The mouse lived in a little house inside of a very big house, with Mary. Even though Mary has been warned to stay away from mice—and Mouse has been warned to steer clear of people—the two can't help but peek at one another. Side by side, they grow up, go to college, get married, and have children of their own—Maria and MouseMouse. And then one day, Maria and MouseMouse do something surprising . . . something their parents never did. They actually come nose-to-nose and speak to one another!
