In the year 2200, Aline Ruby, a tenacious private detective, and her android partner Carlos Rivera are hired by a wealthy businessman to capture a notorious hacker on Earth. Back on Mars, a new case draws them into the depths of Noctis, the Martian capital, in search of Jun Chow, a missing cybernetics student. Noctis is their city—a libertarian utopia made possible by advances in robotics, a symbol of a future aimed at the stars. As their investigation unfolds, they confront the city’s darkest secrets: corrupt institutions, trafficking, brain farms, and the machinations of all-powerful corporations. But cyber-enhanced killers are also after Jun Chow. Aline and Carlos launch into a desperate race to save the young woman who, unknowingly, holds a secret that could threaten the fragile balance on which their civilization rests.
