Wealthy, wrathful Silvergarde has fallen, but one of its conquerors isn't celebrating. Jailed for betraying the rebellion that brought the floating city to its knees, Joslin is ready to hang up her ideals—until she overhears the confession of an enemy officer. Her cellmate Gavia may despise the rebels, but she is Silvergarde's youngest airship pilot, a formidable fighter, and an invaluable ally. While their methods clash and their goals may not align, the two are pushed together by necessity and undeniable attraction. With time running out, a dishonored rebel and a prisoner of war may be all that stands between a successful coup and Silvergarde's complete annihilation.
