George R. R. Martin's The Hedge Knight III - The Mystery Knight (2017)

A full-color graphic novel edition of The Mystery Knight, set in the bestselling Game of Thrones world, 90 years before Game of Thrones begins! The Mystery Knight is the third novella in the "Dunk and Egg" series, a sort of prequel to A Game of Thrones, given that it highlights a key bit of history leading up to those events. Our heroes are the noble but impoverished hedge knight Duncan and his bold squire, a boy known as Egg, but whose real name is Aegon Targaryen, and who will someday become King Aegon V the Unlikely - and Daenerys' great-grandfather.
