Cast in Sand - Atlas Cycle

On a failed expedition to the heart of an ancient space station, Edwina wakes in a land of fierce warriors and drifting sands, in a mechanical body that is not her own. With no memory of why, or how many bodies have come before this, one thing is clear: she's trapped and time is running out. An ancient citadel looms over the barren land and a cruel sultan rules the scattered people. Edwina finds a new body, one real enough to feel human, and strong enough to challenge the sultan.
But the android body comes with human weaknesses, and like the others it has a mind of its own. When her allies begin to quarrel, Edwina must find a way to make empathy and hatred work together. To do that, she may just have to listen to what the android is telling her. This is Station Atlas, where the fall of humanity is long forgotten, where history becomes fantasy, science becomes magic, and basic survival is high adventure in a strange, fragile world.
