Two Ghosts

Jade, Steve and Bucky have been best friends since they were four years old, and although a lot of things could tear them apart, they always find a way back to each other.
Jade Williams has been SHIELD's best kept secret until Steve Rogers is found on the ice, which will unchain their destiny in a way that they would have never guessed...including discovering that Steve's best friend and the love of Jade's life, Bucky Barnes, is still alive.
She was given the supersoldier serum after both Steve and Bucky were announced dead, what can a woman do with such power running though her veins?
