Arrietty isn't your ordinary fourteen-year-old girl--she is small enough to make her home under the floorboards of a typical house. Everything she and her family have they've borrowed or made from things they've borrowed--and only a little at a time, so the ladies of the house won't notice. A boy named Shawn discovers Arrietty, and before long a friendship begins to blossom. Based on the classic novel by Mary Norton, The Secret World of Arrietty is a delight for all ages.
