A Knight of the Seven Kingdoms by George R.R. Martin

A century before A GAME OF THRONES, two unlikely heroes wandered Westeros...
A Knight of the Seven Kingdoms compiles the first three official prequel novellas to George R.R. Martin’s ongoing masterwork, A Song of Ice and Fire.
A young, naïve but courageous hedge knight, Ser Duncan the Tall towers above his rivals – in stature if not experience. Tagging along with him is his diminutive squire, a boy called Egg – whose true identity must be hidden from all he and Dunk encounter: for in reality he is Aegon Targaryen, and one day he will be king. Though more improbable heroes may not be found in all of Westeros, great destinies lie ahead for these two...as do powerful foes, royal intrigue, and outrageous exploits.
A Knight of the Seven Kingdoms is a must-have collection that proves chivalry isn't dead - yet.
