You, Summer, are taken in with the Avengers. After you meet Natasha, it gets a bit better. But- it took some time, but during some game, you find out you're actually trapped. That's not the problem- the problem is that Natasha is trapped. On Vormir.

This is a Nat end game story through and through. I'm going make one for a Wanda as well, if you want the best of both worlds check my story swapping sides

Book 1: All Anastasia really believes about herself is that she was born to kill, that she has no place in this world. She is one of the worlds deadliest assassins, raised in the new and improved Red Room. Now 17, filled with trauma and rage. She is recruited by SHIELD after being captured, will she work with them, or against them? And what relationships, if any will she form on the way? Possible trigger warning for mental health, abuse and other things. *I don't own any of the MCU characters, this is fan fiction* *I don't think this will follow the exact story line of the MCU, but I haven't decided yet. It at least starts after age of ultron, but I don't intend to have a civil war, because that movie made me sad seeing them all break up haha, also shield hasn't fallen and still exists closely linked with the Avengers, but HYDRA no longer has moles in it*
