Skallagrigg

Note! This book isn't a fantasy book, but the central notion of this book is actually a fantasy idea and the story itself is a quest in the fantasy tradition.

Unites Arthur, a little boy abandoned many years ago in a grim hospital in northern England, with Esther, a radiantly intelligent young girl who is suffering from cerebral palsy, and with Daniel, an American computer-games genius. This book has been made into a BBC film.
