A tower has reappeared in the dark forest — tall, ancient, and suffused with powerful magic. Legend says something is hidden inside it. Everyone who has ever entered has failed to come back out. Deep in the forest, a witch wakes to a voice calling her name from somewhere she cannot identify. She does not remember much about who she is. To recover her memories and fulfill what she senses is her destiny, she picks up her staff, puts on her hat, and pushes open the tower's heavy doors.
