A Golden Path (Asoiaf/Dune)

Paul Atreides is reborn north of the Wall, amongst the wildlings with the Long Night hanging above his head like an executioner's blade. The Seven Kingdoms must be unified but with a mad man on the throne, squabbling ambitious nobles, and bad actors a rebellion is imminent. The only way to save the world is to find a way into the Kingdoms... and onto the Iron Throne itself.
