The Forged (The Forged #11)

Victory and her rogue Forged team infiltrate the Empire's most impregnable stronghold-a planet-sized, high-value, high-tech armory-to thwart the Eternal Empress's next assault. With no armor and no weapons, the renegades go head-to-head with a rival Forged team that has both, and a thirst for vengeance, to boot.
