When mercenary commander Tahim fled the Battle of Virginis with ISF technology—after betraying his allies—Jessica Keller wasn't about to let it slide. Tracking him to the Diadem System, she infiltrates his headquarters to reclaim what's hers.

But nothing is ever simple. Jessica's capture leads to a trial that's anything but fair, forcing her into a deadly gladiatorial contest where survival is not expected. Meanwhile, her crew discovers something far worse than stolen tech: Tahim's family is trafficking thousands of enslaved AIs.

Now Jessica must fight for her life in the arena while her crew orchestrates a daring rescue operation. With local authorities corrupted, deadly combat mechs closing in, and an entire moon's military on alert, the team will need every trick they've learned to pull off the impossible.

Some rescues require more than stealth and cunning—they require a distraction loud enough to shake a world.
