Peer reviewed book chapter in Transmedia Harry Potter: Essays on storytelling across platforms. As a foster carer, I have witnessed first-hand the therapeutic benefits of Harry Potter for children in out-of-home care. My husband and I read the series to our eight-year-old foster child, who revelled in the vitality and vividness of J.K. Rowling’s wizarding world: the sights and sounds of Diagon Alley, the excitement of a quidditch match, and the awe-inspiring grandeur of Hogwarts castle. But for him, and the hundreds of thousands of children like him living in care around the world, Harry Potter is more than just an engaging literary experience: it is salvation.
