Reborn to be the Dragon Queen

In the life before this one, Arya fed the red dragon Lucien on her own blood until he was strong enough to lead the tribe. Her stepsister Cecelia took the black dragon Raegar, whom nobody wanted, and had a hard time of it. Cecelia's answer was to take Lucien from her and then kill her. Arya opens her eyes at the beginning of it all, knowing how it ends. This time she goes to Raegar, the dragon the tribe treats as cursed. She breaks the seal on him without meaning to, and what comes out from under it is not a curse. He is a prince of the dragon line, and he has been sealed for reasons that have nothing to do with what she was told. Cecelia and Lucien set out on the same path they took last time, toward the leadership and the marriage they took from her, and neither of them knows that the woman watching them do it has already seen how it ends.
