Then you might like David George III's Kirk volume in his Crucible series. It takes on those events in a novel fashion, but without making Kirk superhuman, while still giving his story a great ending.
That was a great short story padded out to novel length, honestly.
But then, the entire Crucible trilogy was made up of a few good ideas glued rather awkwardly together. McCoy was the only one of the bunch which really *needed* the "City" link at all.
