Winter is coming [Captain America the Winter Solider]

( In this story, Steve and Bucky are both super soldiers and Bucky has a sister.)
Everyone knows the famous Steve Rogers and Bucky Barns, but not many know of Bucky's sister Ruby. That should because she died a long time before ... Or at least they thought she did.

Steve and Bucky have a new mission. The Winter Solider. According to the Black Widow, the winter solider is just a ghost, so they team up with the black widow and the falcon to stop H.Y.D.R.A and the Winter Solider, but it might be harder than they thought.
