Ed Brubaker accomplished a great many things with his incredible run on Captain America (A run which is just wrapping up with Brubaker's departure after scripting Cap's adventures for eight years.), but if you wanted to sum that run up in just a few words, those words would have to be: Brubaker brought back Bucky.
Yes, it's true Brubaker's run also saw Steve Rogers -- Captain America -- killed, but we all knew Steve would be back, and sure enough, he is. But Brubaker's run took one of the pillars of comics continuity, the fact that Cap's World War II partner, Bucky Barnes, was dead, and changed that reality. Through the course of the first 20 issues of Brubaker's run, we learned that the Soviets recovered Bucky's body, reanimated it, replaced the broken parts with cybernetics, and reprogrammed Bucky's brain to make him the ultimate assassin. They renamed him the Winter Soldier and kept him in suspended animation, reviving him only briefly for specific missions over the years. Few people left alive had glimpsed the Winter Soldier in the intervening decades, thus the assassin's true identity was not known.
Brubaker wove a narrative wherein Cap discovers the true identity of the Winter Soldier and sets out to rescue his former partner. He succeeds in not only finding Bucky and freeing him from his controllers, but also in restoring Bucky's memory of his true identity and all of the crimes he committed as the Winter Soldier. As if that weren't enough to deal with for the former sidekick, it isn't long after these events that the Red Skull and his agents appear to have succeeded in slaying Captain America, and Bucky must also deal with that grief.
For a time after Steve Rogers' death, Bucky picked up the shield and mask and became Captain America, not so much because he felt worthy to do so but more to keep someone else from doing so and disgracing the memory of his friend. While serving as the new Cap, Bucky and several other heroes learned that Steve Rogers was not dead, but merely "dislodged in time" (Just go with it, or better yet, pick up the issues and read 'em; they're good stuff!). They rescue him and for a very brief time, there were two Captain Americas in the Marvel Universe.
Now, Bucky has again adopted the name Winter Soldier, but this time he's working to make up for the things he did while under Soviet control. These first two issues read very much like some of the better issues of Captain America under Brubaker's hand. Even the artwork is similar as Butch Guice was one of the frequent Cap artists during Brubaker's run. Along with Bucky is the Black Widow, another former Soviet operative now working with America's forces. This book reads like a natural continuation of what Brubaker started, and I imagine it will continue to do so as long as he helms the adventures.
