The Rogue Prince, or, the King's Brother by George R. R. Martinit took me a long time to put my hands on this considerably new graphic novel by George R. R. Martin but now when I got it. I finished reading The Rogue Prince, or, the King's Brother in one night and I can review the this graphic novel like I did with the Dunk and Egg tales.
The Rogue Prince, or, the King's Brother graphic novel just like The Tales of Dunk and Egg is completely different than the ASOIAF books, on the other hand it doesn't really resemble any of the 3 Dunk and Egg tales either. The Tales of Dunk and Egg focused mostly on the two main characters from the title itself with minimal contact to the royal Targaryen family every once in a while. There was a significant presence of the Targaryens in The Hedge Knight and a small attendance in The Mystery Knight but it was nothing compared to what we got to read about in the Rogues.
