The Pact

Thirty years after the civil war, the Targaryens return to the continent they almost shattered, but they are not the greatest peril faced by the Seven Kingdoms of the Septate of Westeros. Other enemies threaten to tear apart the Septate from within, and what King Eddard Stark knows of them could destroy his family as well. His only hope of keeping his loved ones and Westeros's unity intact may be to convince his elder daughter, Sansa Stark, to honor the Septate's millennium-old Marriage Pact, and even that may not be enough to keep the continent and its thousand-year-long peace from disintegrating.
