Enemy of God (The Arthur Books #2)
Embattled, honorable executive Arthur faces revolt by Lancelot and betrayal by Guinevere. King Mordred comes of age, but should he be king? Arthur is faced with more than one dilemma as quests and plots, treachery, lies, and mysteries proliferate.  Adultery and violent revenge strain Arthur's alliances, horrifying even war-hardened narrator Derfel Cadarn and endangering his beloved family.Little faults plague this book and its prequel. Bernard Cornwell insults Welsh princes with the Saxon title "Edling," and someone should tell him what gold weighs--he has a gigantic gold cauldron carried on one man's back and generally throws gold bars around like wood chips. However, his rearrangements of the well-known tale are ingenious and plausible, and these books are very entertaining.
