Wagers, KB - Behind the Throne (Indranan War #1)

Behind the Throne begins K. B. Wagers's action-packed science fiction adventure, with a heroine as rebellious as Han Solo, as savvy as Leia, and as skilled as Rey.
Hail Bristol has made a name for herself as one of the most fearsome gunrunners in the galaxy. But she can't escape her past forever: twenty years ago, she was a runaway princess of the Indranan Empire. Now, her mother's people have finally come to bring her home.
But when Hail is dragged back to her Indrana to take her rightful place as the only remaining heir, she finds that trading her ship for a palace is her most dangerous move yet.
In a world where the only safe options are fight or flight, Hail must rule.
