When Ed Brubaker took over the writing duties on Captain America back in 2004, the character was on life support. The previous decade saw sales of the book plummet as a new, and far more jaded, breed of comic book fan had grown tired of the cookie cutter world of the Star Spangled Avenger. But in his very first issue on the book, Brubaker proved himself by instantly injecting new life into Captain America, and helped launch the current renaissance that the character is in the middle of now. 

Unfortunately, in an interview with The Comics Reporter, Brubaker confirmed that he is leaving the newly-relaunched Captain America title to concentrate on more creator-owned books, like Image Comics' Fatale

Partly, it's the beginning a shift from work-for-hire to books I own, instead. I hit a point with the work-for-hire stuff where I was starting to feel burned out on it. Like my tank is nearing empty on superhero comics, basically. It's been a great job, and I think I found ways to bring my voice to it, but I have a lot of other things I want to do as a writer, too, so I'm going to try that for a while instead.

Brubaker also explained to the site that the schedule that Marvel wanted him to maintain was simply too much for him to keep up with, especially since he is delving headfirst into the world of film and indie books too. To help ease the transition, Marvel has hired writer Cullen Bunn to co-plot the last four issues of Brubaker's run with him.  Bunn started co-writing the book with issue #15, and Bleeding Cool is reporting that Brubaker's last will be issue #19.

But there is some good news for Brubaker/Marvel fans. The writer also said in the interview that he will most likely continue his work on Winter Soldier, "for as long as I can." So he won't be leaving the Cap world that he created completely.
