Your Betrayal. Naruto Shippuden. Incomplete

Sora Uchiha is twin sister to Sasuke Uchiha and has had a horrible life. Her brother Itachi killed their clan, threw Sasuke and her against a brick wall causing her to lose some memory, and on top of that, Sasuke has left too. Years later, and still part of Team 7, they're getting a new team mate, Sai. Sora will have to dig deeper into her past then she wants to, and uncover the reason why Sai is so familiar to her. But there's more than just memories, both forgotten and unwanted, that is haunting Sora.
