Darkscan. Company Justice, #2

Nobody surprises - or unsettles - readers quite like DeAnna Knippling, veteran author of over 80 books. New Year's Eve. Cheers, champagne, a countdown. The ball drops at midnight-and the Templeton Building in downtown Minneapolis goes dark and silent. The building disappears from all outside contact: no Internet, no phone calls, no wifi, no radio. No way in through the newly sealed windows and doors.
All while a blizzard pounds the city at ten below. Two hundred wealthy partygoers walked into the ritzy high-tech skyscraper. None walked out. Hard-nosed private investigator Frank Mallory, veteran of the sticky gray areas where technology crosses with crime, gets called in for an emergency job:Enter the Templeton Building. Use a pair of AI-powered lenses called Darkscan to navigate the unstable darkness.
Extract the client's ex-wife. Then walk back out. A claustrophobic near-future noir about the savage cost of mistaking obedience for intelligence.
