Lyna stark is the eldest of Ned's children and the one who is unknown. What happens when she gets a taste of freedom and meets the Red Viper?

Ramsay Bolton has taken Winterfell. As the son of the Warden of the North, his only hope of keeping Winterfell is by having a Stark by his side... Sansa Stark is hidden away at the Eyrie. Arya Stark is in Braavos. That leaves only Edda Stark, third child of Eddard and Catelyn Stark, who travels alongside her brother Robb's army. After the Boltons and the Freys successfully trick the Starks into trusting them, they proceed to kill Edda's brother, mother and sister-in-law and capture Edda in what became known as the Red Wedding. From there, they take her to Ramsay.
