The Bright Sword By Lev Grossman

When gifted young knight Collum arrives at Camelot to compete for a place on the Round Table, he quickly discovers that he’s too late: The king died two weeks ago at the Battle of Camlann, and only a handful of the knights of the Round Table are left. And the survivors aren’t the heroes of legend either, like Lancelot or Gawain. They’re the oddballs of the Round Table, like Sir Palomides, the Saracen Knight, and Sir Dagonet, Arthur’s fool, who was knighted as a joke. They’re joined by Nimue, who was Merlin’s apprentice until she turned on him and buried him under a hill. But it’s up to them to rebuild Camelot in a world that has lost its balance, even as God abandons Britain and the fairies and old gods are returning, led by Morgan le Fay. They must reclaim Excalibur and make this ruined world whole again. But first they’ll have to solve the mystery of why the lonely, brilliant King Arthur fell.
