Once again, Annie and Jack are summoned by Merlin to the fantasy world of Camelot. He informs them that the Diamond of Destiny has been stolen and the answer to its disappearance lies within a haunted castle. Jack and Annie, with a young magician named Teddy, find the castle and discover that it is inhabited by four ghosts-a girl, twin boys, and a dog. The ghosts communicate to the three that the problem is the stolen diamond, that it must be retrieved, and that the Raven King has it. The children find and retrieve the diamond, revive the ghosts and their sleeping household, and give the Raven King what his heart most desires.
