Plot The Grey Griffins series follows the story of four sixth graders who live in the fictional city of Avalon, Minnesota. These four friends formed a secret order named The Order of the Grey Griffins, consisting of, Grayson Maximillian "Max" Sumner III (the leader) and his friends: Natalia Romanov (the marshal), Ernie Tweeny (the steward), and Harley Eisenstein (the warden). In The Revenge of the Shadow King, the Grey Griffins discover a link between their 'innocent' card game (Round Table) and a magic book (the Codex Spiritus) which Max discovers in his grandmother's attic. The story focuses on the friendship between the four 'Griffins', and their adventures as they stumble upon one dark secret after another and soon learn that the world in which they lived was much more dangerous than they ever believed. With the help of the Knights Templar (a shadowy organization that protects humanity from the monsters and abuses of faerie magic), the Griffins uncover a plot to hand the earth over to the malevolent Shadow King. In The Rise of the Black Wolf Max and his friends travel to his father's castle in Scotland for Christmas. But even before they arrive, they are attacked by Morgan La Fey, the sorceress they had believed defeated in the previous book. Disaster strikes the Sumner Castle, and Max and his three best friends set off on a round-the-world journey to collect the three scattered pieces of the Spear of Ragnarok. In The Fall of the Templar, the Black Wolf Army, now under the leadership of Max's father, attack the Templar, plunging the two forces into a covert and shadowy war. But this time, the stakes are larger than just the lives of the soldiers. Lord Sumner, with the Spear of Ragnarok, plans to destroy the world, which he believes to be corrupt, in order for it to be reborn. Once again, the Griffins set off on another treacherous adventure to find answers, this time deep below the surface of the Earth in the Underworld. List of novels Main TrilogyThe Revenge of
