This exciting reading book tells the story of Kat and AIDE Lock, the world’s first AI detective. Together, they investigate a murder with an apparently political motive, but soon the case develops into something far more dangerous.
After a large-scale cyberattack shuts down the national power grid, chaos and panic hit the country. Kat and Lock must track down a murderer who always seems to be one step ahead. In a world of deepfakes and digital illusions, intuition is not always reliable.
In this complex case, Kat faces a difficult choice: can she still trust her AI partner? Lock doesn’t just change the way they investigate; it also raises fundamental questions about humanity to a breaking point.
Find out whether Kat is able to stop the culprit before the lights go out for good.
