The Assassin — P.J. Fox

Scion of the Empire's oldest house. Spy. Assassin. A man who, some claim, has no soul. Ceres Mara Sant is no one's idea of a hero. Which suits him just fine. He's not trying to be anyone's hero; only get in, do the job, and get out. The job being a rogue assassin, a former best friend, whom he's been hunting across the galaxy. But when he finds himself in one of the worst slums he's ever encountered, on a backwater planet the entire population of which he loathes, he's distracted for the first time: by a grubby and pinch-faced street urchin, bold -- and foolish -- enough to thwart him. This is the tale of what happens next.
