Once there was magic in Britain. There were dragons and wizards and green knights and kings who pulled swords out of stones. But now, the doors to the Otherworld have closed. Young Hag has grown up believing her mother and grandmother are the last witches in the land. But when tragedy strikes, she turns her back on these tales. Where is their magic when they really need it? Then one day they find a changeling in the woods. Confronted with real magic at last, Young Hag has no choice but to believe. She sets off on the greatest quest of her life; but can Young Hag bring the magic back? Or will she become a footnote in the tale of famous kings and wizards? From the acclaimed creator of Glass Town and The One Hundred Nights of Hero comes a dazzlingly imaginative escape into the world of myth. Young Hag ingeniously reinvents the women in Arthurian legend, transforming the tales of old into a heart-warming coming-of-age story.
