Captain America Bucky Barnes Winter Soldier Steve Rogers Fan Fic - The Constant

Sergeant James Barnes thought he knew what he wanted in life. He went to war as a young confident soldier who thought he could cope with anything - safe in the knowledge that the person he loved the most would always be there for him. But then he is broken. Abused. All he wants is to get back to Steve, back to a life that now does not exist. He may as well be in Hell. Perhaps he is.
You never asked for this life. It chose you. And you are forced to watch as the man you love is turned into something else - something he would find horrifying. All you can think is that he needs to be reunited with his first love to be saved...but where will that leave you?
Spanning over 70 years and three lifetimes, this is the story of the Winter Soldier.
