The Long Road Home (гет)

The Witch says that the only cure is to find the Blue Rose of the North and raise her in the shadow of the dragons. Only if they do so will the Queen's womb carry. If not, she is doomed to lose all her babes as she has lost her Princess.
Rhaella Targaryen takes matters in her own hands and has the sole daughter of House Stark brought into the folds of her own family, to raise along with whatever children the Seven see fit to give her. But as her own daughter has died and she births the King but sons, Lyanna Stark becomes more than a simple charm. When the Blue Rose starts blooming she is given to the eldest Prince, Lord of Dragonstone and heir to the throne.
Yet matters are seldom that simple. The words of witches do not make a happy marriage, nor do they build a home. In times of turmoil and strife is it possible for love to prevail, or is chance too strong a foe?
AU! Lyanna is raised at court and is no less of a Stark despite her Targaryen upbringing.
