Consintration Camps, Subject One ( Bucky Barnes FF )

I think the title gives your the gist.But here is a simpler version.
A girl was taken from her mother in Sakovia. When she was hardly one. and raised in Consintration Camps controlled by Hydra agents her whole life. every two years. she goes to a knew camp. she spent 14 years getting abused, raped, shot at, starved, and worked to death.
but as she watched the.young children around her die, and as she dug there graves... she always ended up being the last survivor... and if she wasn't. she would fight the rest to the death.
she has no name... but she is called....
Subject One.... what would happen if the Avengers found her just after hydra injected her with the last bit of Super soldier serum? would this so to seem immortal teenage girl become more valuable to those left in hydra.... or would she become a lost cause? She meet James Barnes, who she finds looks oddly like her.
Will Bucky admit his secret to her? Will she find her purpose? Will the world find they need her in the end?
