The Hedge Knight by George R R Martin

In George R. R. Martin’s The Hedge Knight, a towering squire named Dunk assumes the mantle of knighthood following the death of his mentor. Seeking glory at the Ashford Meadow tourney, he unwittingly befriends a bald stableboy named Egg, who is later revealed to be Prince Aegon Targaryen in disguise. The narrative reaches a climax when Dunk strikes Prince Aerion to protect a commoner, leading to a rare and deadly trial of seven to determine his guilt. Though Dunk’s life is spared, the battle results in the tragic death of the crown prince, Baelor Breakspear, who fought on Dunk's behalf. Ultimately, Prince Maekar allows his son to continue traveling with Dunk, cementing a journey that pairs a humble hedge knight with a future king.
