Summary "As of today, Edward Elric had been missing for four months, two weeks, and five days."
Here is CH. 11: The next day, they did another successful transmutation. And another the day after that. And another the day after that. Four days of successes passed and the change in Edward was becoming more apparent with each day.
Start from the beginning here.
ETA: I also wanted to pimp this awesome Number Twenty-Eight fanart of chimera!Ed that taylowolf did for me. Anyone who reads the fic should go see the awesomness of this picture.
