The Indranan War, book 3: Beyond the EmpireK. B. Wagers2017

Gunrunner-turned-Empress Hail Bristol was dragged back to her home planet to take her rightful place in the palace. Her sisters and parents have been murdered, and the Indranan Empire is reeling from both treasonous plots and foreign invasion.
Now, on the run from enemies on all fronts, Hail prepares to fight a full-scale war for her throne and her people, even as she struggles with the immense weight of the legacy thrust upon her. With the aid of a motley crew of allies old and new, she must return home to face off with the same powerful enemies who killed her family and aim to destroy everything and everyone she loves. Untangling a legacy of lies and restoring peace to Indrana will require an empress's wrath and a gunrunner's justice.
