Just putting in my vote for ghiaman74's
fantastic Dominion War tale, Nightingale's Song
. Fantastic action, well drawn characters, drama, angst, and oh yeah... The Badlands!
The story is posted here on the fanfic board.
series offers a marvelous mix of canon and original characters aboard one of the most professional yet fun-filled starships in the Fleet. These people work hard, and play harder.
These stories are very much worth your time.
