Fleeing the humans whose love she craves, Face has hijacked an alien ship and headed for Mars. But the Martians, who colonized their desert planet to escape Earth's high-tech decadence, did not invite the soulless android. How will Face, part of the first artificial mind with fully general intelligence, win over a city of luddites - all while out-thinking her sibling AIs as they battle to control the body they share? The Crystal series darkens in this restless dance through AI, game theory, and truly alien minds.
