had. Fueled by jealousy, Ray has sworn to make Max's life miserable. Their rivalry is exacerbated when Ray decides to barter with Oberon, the Shadow King. In exchange for otherworldly power, Ray must vow to serve Oberon for the remainder of days. In Ray's opinion, that was hardly a penance for the promise of destroying Max. Lord Sumner: Max's father. Turns on Max, revealing he was using Max to get the Spear of Raganrok, then Max takes revenge Annika Sumner: Max's mother. She is not always kind to Max, but her intentions are secretly for the best. Hannah Sumner: Max's little sister. She never really says much until the last installment of the Grey Griffins series. She can immediately tell that Max is not her actual brother from the alternate universe they are sucked into by the Paragon machine. Raven Lugosi: While everyone fears the changelings, the changelings fear Raven. She is a Quebecois French Canadian, and does not say much, but rather glares at all the others. The Custodian: The guardian of the Underworld. Reception and criticism The Children's Literature Review states that The Revenge of the Shadow King'' is "imaginative" and that "the story's fast-paced, adventure plot is compelling" but that it "lacks depth, as it fails to connect with the larger question asked by great fantasy literature". The review concludes, "Overall the book is a good read, even if it is not great literature." References External links Orchard Books, an imprint of Scholastic Inc.
