excellent SF Princess Hailimi Bristol is the spare, she decides to run away and have an interesting life while also investigating her father's death. She becomes a gunrunner and changes her appearance. The story opens with her losing a battle and being taken by the Indranan trackers back to her homeland and the news that her family are mostly dead and her mother is dying. She's the last heir from her family.  Now she has to survive the random attempts to kill her and find out what's going on and try to accept that she's going to be in charge in a matriarchial society where there's revolution in the air, and another empire who have plans.
 
I really enjoyed it and passed it on to my husband for him to enjoy too.
