"A modern fairy tale" it says on the cover, and that is accurate.
Fay Orr is lost in modern London, cut off from her life by the death of her only daughter. Running through London late at night, she is drawn into the fantastic world of London Beyond, from where she sets out on a dangerous, puzzling and terrifying quest to find and restore her lost daughter.
Joanne Harris weaves song and myth into her story, always keeping at the centre a devastated mother who has lost her child.
Beautifully illustrated by Bonnie Helen Hawkins (although for someone like me, with a phobia of butterflies and moths, some pictures are disturbing!)
