It's the summer holidays. And suddenly there's a strange boy at the bottom of Flynn's garden. Soon, she and her wayward brother Sam are walking out of the house in the middle of the night and crossing four fields to find him again. But as well as the boy, Flynn and Sam find a whole gang of runaway kids.
