When eleven-year-old Edie Winter finds a strange box on the London Underground, she plans to hand it in at her dad’s Lost Property Office. But inside the box is something incredible—a family of tiny, winged people called Flits.
The Flits need Edie’s help: they’re low on snacks and missing their brother, Jot. With rice crispies, biscuits, and bravery, Edie sets out on a magical mission to bring him home.
