YN was taken from her family during world war 2 by HYDRA. The reason they took was because she was strong and killed four HYDRA soldiers just to protect her uncle even though he still ended up dying. She was only Five. They put her on ice the same time as James Barnes. Fifty years later when they try to use her she escapes. But only to be found by the avengers, but mainly the winter soldier. A/N: I own no one! There will be some action scenes, and the reader won't say very much, Bucky might adopt her.
