Pendragon Rising: The Heir of the Lance by JA Graham:
 
Camelot was once Arthur’s kingdom— Now it bends beneath the reign of King Mordred Lot... The only memory of Arthur is a lance, lodged in stone, unmoved.

Arion, a simple squire hoping only to earn a place among Camelot’s knights, never expected to touch it. He definitely never expected to pull it free. When Ron—the legendary Lance of King Arthur—awakens in his hands, the sky cracks with lightning and King Mordred declares him a traitor. Overnight, Arion becomes Camelot’s most hunted.

Now on the run with two friends and a monk, who knows more than he says, Arion must uncover the truth about the lance, the old legends, and the power awakening inside him. Because if the lance chose him… then it threatens the reign of the King and all that he's built.
