From the publisher:
The Clock family—Homily, Pod, and their fourteen-year-old daughter, Arrietty—are tiny people who live underneath the kitchen floor of an English manor. All their minuscule home furnishings, from postage stamp paintings to champagne cork chairs, are “borrowed” from the “human beans” who tromp around loudly above them. All is well until Pod is spotted upstairs by a human boy! Can the Clocks stay nested safely in their beloved hidden home, or will they be forced to flee?
