Winter Soldier: Resurrection (джен)

In 2024, Bucky Barnes follows a lead about more super soldier serum that takes him to Siberia. He encounters the unexpected and finds himself in 2014, shortly after the Winter Soldier vanished.
This is a COMPLETE, STAND-ALONE story but does have two stand-alone sequels (different timeline branches - one that goes into Falcon and The Winter Soldier's timeline and the other that is post-Age of Ultron). You can head directly from Part 1 into either Parts 2 or 3 (since 2 and 3 are independent of one another).
