It’s 2042, and America’s second civil war rages.
Detective Jimmy Hidalgo tracks a serial killer whose first victim was Jimmy’s best friend, in a San Francisco on the brink of social insurrection. The killer has a terrifying new way of murdering her victims. Salvor Becky Wiley recovers a mysterious object from burned out suburbs in a balkanized Los Angeles. She does not sense the importance of the enigmatic artifact until the LAPD and FBI try to seize it. As Becky realizes that her salvage is too hot to handle, and as Jimmy concludes that the man paying him to find the killer is an extraterrestrial, this slow-motion apocalypse shifts into high gear. Pursued by cops and aliens, Becky and Jimmy converge on the Palm Springs Free City in secessionist Aztlán. When exotic artifact and serial killer meet, the near cataclysmic confrontation and the galaxy wrenching conclusion will determine the fate, not merely of Jimmy and Becky, but of all humanity.
