Miniature people who live in an old country house by borrowing things from the humans are forced to emigrate from their home under the clock.

"In a secret world hidden beneath the floorboards, little people called Borrowers live quietly among us. But when tenacious and tiny Arrietty is discovered by Shawn, a human boy, their secret and forbidden friendship blossoms into an extraordinary adventure"--Container.

An amateur witch, along with three precocious orphans, flies into one fantastic adventure after another aboard a bewitched bed to save the country from hostile invaders.
