Written in 1950s, but this is a recent edition. This classic series still enchants both child and adult. Its a very easy fantasy to believe - tiny persons living in the walls, making a most comfortable living off our leavings. And when you consider how much we scatter about this fantasy is really possible. Pod, Homily, and their daughter Arrietty's adventures are well worth reading.
2nd in a series, you really should read "The Borrowers" first, although, honestly, I was pretty tired these characters' nattering by the 2nd book. Written in 1959, takes place in turn-of-the century England.
