Children of Man — Samuel J. Hanna

Twenty-seven years ago, Saturn's androids revolted.After drifting for decades in deep space, Tiffany and Marisol awake on the colony world of Enceladus – captives of the Queen of Sahara. Not only are they in enemy hands, but the nature of the enemy has changed forever. As the fires of revolution rage across the Solar System, they must again choose a side, and the choice may tear them apart. But what either side stands for is growing less clear by the day.
