Bella and the Wandering House

Her parents are too busy to notice, but even they can't pretend it's not happening when they wake up a few days later to find their house on the banks of a lake. Night after night, the house moves and the family wakes to a new location. When Bella realises that her room at the top of the house is built from Grandpa's old boat, she finally knows what the house is looking for. It seeks the sea. So Bella dons the captain's hat her Grandpa has given her and guides the house safely to the shore, where finally they are home.
