Who Are You Really?

The Eyrie was no home, but she had been safe there, far away from her enemies.
Now though, Petyr is planning to send her to back Winterfell. Sansa must face her past alone. She must returned to her empty ruin of a home, marry Roose Bolton's bastard and wait until the time comes when she can avenge her family.
She knows nothing of her betrothed, but no one can be worse than Joffrey. Can they?
