Winter Soldier's Summer

You are the newest Avenger. You're a super soldier, the last of a reserve of sleeper agents, kept secret from even most of Hydra. You were saved and taken in by Captain America himself, Steve Rogers. A year later, he discovers the fate of his best friend, Bucky Barnes, and now he's out to save *him*, and you're tasked with helping to bring him in and reintegrate him.
