From the back of the book:
"Recent raids by Periphery pirates have devastated the planet Bryceland, and the world's ruler seems powerless to stop these marauders. Fearful and furious, Bryceland's citizens talk of revolution, while forces behind the scenes plot a military coup. Only one woman can keep Bryceland from succumbing to civil war: Samantha Davion-Harland, beloved daughter of Bryceland's duke. But the pirates abducted Samantha on their last raid, thaking her somewhere deep in the Periphery. The duke engages your band of mercs to rescue his daughter. The leaders of the coup will do anything to keep you from succeeding."
