As Blackwater Bay cools, the victors consolidate their power and rebuild King's Landing. But new challengers for the Iron Throne rise from the most unexpected places.
Characters old and new must navigate the demands of family, honour, ambition, love and - above all - survival, as the Westeros civil war rages into autumn.
Based on the bestselling fantasy book series by George R.R. Martin, Game of Thrones is an epic story of treachery and nobility set on the continent of Westeros, where summers and winters can last years, and only the lust for power is eternal.
As Season 3 begins, the Lannisters hold absolute dominion over King's Landing after repelling Stannis Baratheon's forces. Yet Robb Stark, King in the North, still controls much of the South as well, and has yet to lose a battle.
In the Far North, Mance Rayder has united the wildlings into the largest army Westeros has ever seen. Only the Night's Watch stands between him and the Seven Kingdoms, but nobody knows what happened to its Lord Commander and the force he led beyond the Wall.
Across the Narrow Sea, Daenerys Targaryen - reunited with her three growing dragons - ventures into Slaver's Bay in search of ships to take her home and allies to conquer it.
