When Princess Cassia Rose fled her home world of Eturia to escape an arranged marriage, she had no idea her sudden departure would spark a war. Now after two years hiding as a ship hand, she is finally returning to her beloved home but not in the way she imagined. Shackled by bounty hunters, she is violently dragged back to account for her crimes. Her only solace is that the Banshee crew managed to evade capture, including Kane Arric, her best friend...with occasional benefits.

Meanwhile, Kane and the rest of the crew of the Banshee plan a desperate rescue mission. But when they arrive on Eturia, Cassia isn't exactly in need of heroics -- she's claimed her birthright as Eturia's queen, but has inherited a war-torn planet simmering with rebellion. Cassia must make alliances, and Kane, the bastard son of a merchant, isn't a choice that will earn her any friends. Kane knows he will never find someone to replace Cassia -- and is certain she returns his feelings -- but how can he throw away his own promising future waiting on a queen?

When the outer realm is threatened by the dangerous Zhang mafia, Cassia, Kane and the rest of the Banshee crew uncover a horrifying conspiracy that endangers the entire universe. In the face of unspeakable evil, Cassia must confront her own family's complicated legacy on Eturia and decide once and for all who her real family is.
