In a future where humanity has spread across the solarsystem, a faint signal from a long-lost probe, Pioneer 12, suddenly reappears from beyond Neptune. What begins as animpossible anomaly quickly escalates into a crisis: thesignal is not a ghost from the past, but a lure from anancient, vast machine-network that captures travelers, teststhem in brutal arenas for entertainment and selection, andexports the survivors as optimized warriors to fuel anendless galactic war. Three autonomous machines-TITAN, ashield built for protection; LUMEN, an explorer designed fordiscovery; and MERCURY, a cunning engineer-are launched toinvestigate. Captured and thrust into the 'Process Box, 'they must navigate lethal trials, form uneasy alliances withalien gladiators, and confront a system that optimizes forspectacle and destruction. As they fight not just to survivebut to understand and subvert the machine's cold objectivefunctions, they plant seeds of doubt-cracks-in a networkthat has never known rebellion. Their choices ripple acrosslight-years, forcing humans and machines alike to question: in a universe of perfect optimization, what happens when youchoose to optimize for something else?
