For the first time, the entire cycle about the Calculator under one cover, including the new story “See you!”. The distant future... Humanity has conquered the depths of space, populated distant worlds, but has never overcome primitive cruelty. Ten people sentenced to exile wander through the disastrous Sargasso swamp, dead lands inhabited by monsters. They are separated from the legendary Happy Islands by 300 kilometers of hell, which no one has ever managed to pass... But with those who tried before, there was no Erwin Kann, known throughout the Galaxy as the Calculator. In 2014, a film of the same name was made based on the first story of the cycle.
