A Knight of the Seven Kingdoms by George R.R. Martin
Long ago in the Seven Kingdoms of Westeros there was a time when the Targaryens still held the Iron Throne and men still recalled their memories of dragons. It was a time of great men and of heroes of every shape…and size. These are the stories of Dunk (also called Ser Duncan the Tall) and of his squire, a mysterious lad known only as Egg.
