Once there was magic in Britain. There were dragons and wizards and green knights and round tables and kings that pulled swords out of stones. But now, the doors to the Otherworld have closed, and the magic is gone. All that is left are the stories of those bygone days. Young Hag, her mother and her grandmother, Ancient Crone, are the last of the witches in Britain. At least, that's what Ancient Crone says. Young Hag has grown up hearing those tales and believing in her the power of her Grandmother. But when tragedy strikes, and their world is shaken, Young Hag turns her back on magic. She is sick of the tales of family curses, faerie doors, lost magic, and ancient swords. If they are witches, where is their magic when they really need it? And then one day they find a changeling baby 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; to bring the magic back to Britain. But when faced with magic and myth, can Young Hag put aside her doubts and fears?
