Mistworld

A planet of outlaws, rebels, and misfits must fight back against the corrupt empire in a novel by a New York Times-bestselling author: "Lots of action." --Science Fiction Chronicle

Long before the start of a galactic rebellion, Mistworld is just another rebel planet, cut off from the fruits of empire by a punishing blockade. In a spaceport where ships hardly land anymore, and any piece of high tech is worth far more than its weight in gold, a medieval order has imposed itself on this once-rich world: The strong rule, the weak perish, and no one is too rich to steal.
Investigator Topaz is one of the few honest people left on this cutthroat planet. With her husband, Sergeant Michael Gunn, Topaz does what she can to keep the crooks who run Mistworld in check. But when the corrupt Empire devises an unprecedented scheme to attack the ESP shield that guards Mistworld, Topaz is the only one who can save the planet from being overrun. An enemy fleet lurks just off world--but it is the enemies at home whom Topaz and Gunn should fear the most.
