The Revenge of the Shadow King by Derek Benz and J.S. Lewis is about the Grey Griffins (Max, Natalia, Ernie, and Harley), teens from Avalon, Minnesota who enjoy the mysterious card game Round Table. Little do they know that the cards they play their game with are actually meant to teach them the true history about the Knights Templar and the Shadow King's rise to power. Max finds out that he is a descendant of one of the knights and has been tasked with protecting their secrets from the Shadow King and the evil Morgan LaFey (King Arthur's immortal step sister and murderer). The Grey Griffins go through one adventure after another as they work to conceal the Codex Spiritus, an ancient book passed down amongst the knights, and retrieve the jewel of Titania in order to stop the Shadow King from returning.This book was good. There was a lot of action and some really neat history about King Arthur and the Knights Templar. To me, it felt like the story just kept going and going and going. The teens made mistake after mistake, and had battle after battle with the evil forces bent on stealing the ancient book. This is the first book of the Grey Griffins series.
