The Light Beyond the Forest: The Quest for the Holy Grail is the second book in Rosemary Sutcliff's Arthurian trilogy. This book focuses on the search for the Holy Grail, cutting back and forth between the quests of Lancelot, Bors, Percival, and Galahad. The knights involved in the quest show many virtues: loyalty, self-control, mercy and piety among them. Throughout the quest they realize that they´ll only achieve success if they fight against evil, first of all, within themselves.
Some ideas are confusing. Magic and Christian religion seem to live together with normality, and in some occasions magic seems to have as much power as religion. This is is just something implicit in the book, which, on the other hand only describes events in a legendary world. Though not as clearly as in The Sword and the Circle, the heroes of the novel share honest Christian virtue and piety with the use of unnecessary violence.
