Down on his luck after a bitter divorce, Planetary Union officer Ed Mercer finally gets his chance to command his own ship. Determined to prove his worth and start a new chapter, Ed discovers the first wrinkle in his plan when the First Officer assigned to his ship is his ex-wife, Kelly Grayson. As the new commander, Ed assembles a qualified -- but eccentric -- crew, including his best friend, Gordon, who has problems with authority but is the best helmsman in the fleet; Dr. Claire Finn; Bortus, an alien from a single-sex species; Isaac, an artificial life-form from a machine society; navigator John Lamarr; Alara Kitan, a young, inexperienced security officer; and Yaphit, a gelatinous creature.
