About the book: 2019 / Nick is the captain of a space repair ship. He is overweight, but this, in general, never bothered him. However, the caring artificial intelligence insists: “Body mass index is higher than recommended,” and forces Nick to follow a diet. Grueling workouts, lousy food - Nick patiently accepts the System’s recommendations, but everything changes when a Stranger in purple approaches him in a cafe. And who would have thought that because of this meeting someone else's life would be at stake?.
