This is easily the best Yu Yu Hakusho fanfiction I've ever read. It has amazing characterization, a unique style, interesting takes on the way the characters think, and a plot that's as ingenious as it is entertaining. The fic takes a slightly angsty tone, but that's very justified, and it's an extremely worthwhile read. As of January 2012, it's still being updated, though the author is close to completion.
