The Immortality Gene

No matter how far into the future humanity goes, the problem of workaholic burnout will remain. Gena Petrov, a lead engineer of the "Genetic Perspective" project, goes on a long vacation to properly shake things up. And he has no idea what kind of shake-up awaits him. It all began with meeting a girl whom he named Ksenia. A planet-ocean, a truck you can talk to like a friend, a swarm of Papa Sue ants, and the main—great—problem that Petrov is trying to solve: to grant immortality to humanity.
