Kimballs Green Junior School's newest student is more than a little strange--in fact, she might be the feared daughter of the Erl King! Kevin loves sharing the stories his grandmother used to tell him about trolls and witches with his school friends. His favorite tale is about a scary spook named the Erl King who rides on a black horse at night. But when a new student, Nora Scull, arrives at Kimballs Green elementary school, Kevin begins to wonder if maybe the stories are true. Skinny as a broom and with dark, stringy hair, Nora never laughs, but she's always watching and listening. She also steals and makes Kevin do all sorts of bad things. Who is Nora, and what will Kevin have to do to save himself--and his school?   This ebook features illustrations by Paul Warren and a personal history of Joan Aiken including rare images from the author's estate.
