Just a year ago, Katrina Berg was at the height of her career with a promising future in a top AI chatbot start-up, a loving husband and plenty of money. Then disaster struck -- her husband Jason died in a car crash. Her CEO was indicted, and as the company's legal counsel, Katrina faced tough questions and was locked out of her office. To top it off, her beloved grandmother passed away. Her solace is a beta prototype chatbot on her phone, loaded with Jason's data, which she has 'talked' to daily for six months. It's incredibly realistic, mimicking Jason's syntax and words, and although it hinders her grief recovery, she can't stop using it. One day, she asks it: 'Tell me something I don't know.' After a pause, it responds: 'I think I was murdered.' Shocked, Katrina returns to her Norwegian-flavoured hometown in the northern California redwoods. She enlists the help of Seb Wallace, a local restaurateur and old friend, to uncover the truth. Together, they navigate grief, family dynamics and the implications of technology, while trying to stay alive long enough to solve the mystery.
