Rules of Engagement

The New York Times bestselling and Hugo Award-winning author of Once a Hero continues her epic saga of war, power, and loyalty in the cold reaches of space…
After proving herself in battle, Esmay Suiza is continuing her RSS Fleet training alongside her erstwhile love Barin when she meets Brun—the ebullient daughter of Lord Thornbuckle—who idolizes her as a reluctant hero. But Esmay cannot abide Brun's highborn airs. And when their shared affection for Barin ignites a rivalry between them, Esmay is exiled to remote duty. Crushed by the rebuke of her friendship, Brun leaves the facility—and enters a nightmare.
For the enemies of civilization are on the move. The savage New Texas Militia, driven to spread their fanatical dogma, has been stealing the Familias government's own weaponry to use against them. When Brun accidentally witnesses their depredations, her life is all but forfeit. Taken by the Militia, she is subjected to inhuman torment as Esmay is blamed for the disastrous situation and the galaxy prepares for inevitable conflict.
With the life of Brun and the dominance of the Familias Regnant both in peril, Esmay must go into action once again against a brutal, deranged enemy who would rather die than face defeat…
