A review by myriadreads
After Atlas by Emma Newman

4.0

A fast-paced genre bender, sci-fi/murder mystery. I couldn't put it down! In a future where several large gov-corps rule the world, many people find themselves working under contract just to survive, with no hope of ever living free lives. Carlos is a detective, using the tools of a new age to solve crimes, but his only joy is in coming and eating real food, expensive and hard to come by. When the charismatic leader of a powerful cult is found dead, Carlos will apply himself to the puzzle, though it means confronting a past that he's successfully hidden from for years.
Newman has a gift for bringing a future world to life in the details without being heavy handed. Note: while this follows in the same universe as Planetfall, it is only connected, not a sequel. I think you could read this one as a standalone, or read it first, and still understand the premise perfectly.
