Officer Lon Salonikis had discovered the answer to the information leaks on Freedom Two and was killed because of it. The problem is he never passed on the answer to anybody else. Solar Police Joss O'Bannion and Evan Glyndower (Lon's ex-partner) now must go to the space station and find out why somebody is willing to kill a police officer over something that should be a minor crime.
The first of three sci-fi books set in the future of space, which is treated like a frontier, where law officers are few and far between and life is cheap. The settings are gritty and realistic, a dirty, somewhat pessimistic future. The science is slightly hard, which I like, but most of the focus is on characters and plot, which is also something I prefer. Lots of humor also.
