A new political realignment may be featured in the upcoming book “Winds of Winter.” Tywin Lannister was able to save his House during the War of the Five Kings, but the “Game of Thrones” TV series revealed how Cersei will single handedly break the alliance and put the future of the House in jeopardy.

[Spoiler alert]

Cersei is yet to get her revenge for the Walk of Shame in the book series. The alliance of the Lannisters and the Tyrells is shaky even in the books. If the plot in the TV series is used, then Tywin’s daughter is sure to put the final nail in the coffin of the alliance.

The new alliance the TV series teased was that of Dorne with House Tyrell, facilitated by Varys (Conleth Hill). The two powerful Houses plan to pledge support to Daenerys Targaryen (Emilia Clarke). However, things aren’t that simple in the book series.

Prince Doran had sent his son Quentyn Martell, also known as Frog Prince, to Essos. His mission was to propose marriage to Daenerys. After being rejected, he attempted to tame one of the dragons and died in the process. Will Dorne hold a grudge in “Winds of Winter”?

There is another complication in Westeros. News of Aegon Targaryen, son of Prince Rhaegar Targaryen and Elia Martell, being alive and now with an army has spread. Dorne may decide to side with the young prince in Westeros, rather than the Mother of Dragons who is still in Essos.

If Cersei kills Margaery or any other members of the Tyrell family, the armies of Highgarden may be keen on revenge. The prospect of taking Iron Throne with the help of Tyrells and Martells may be of considerable interest for Aegon.

The only ally left for the Lannisters in “Winds of Winter” would be the Freys. However, even they are being harassed by the Brotherhood without Banners, led by Lady Stoneheart. And if Arya joins her mother to exact vengeance, it is safe to assume that the Twins castles are bound to fall.
