A person can never say with certainty what awaits him tomorrow. And sometimes - not only tomorrow, but literally in a few hours. Having left for a routine application to set up equipment at one of the enterprises, Alexander Speshin did not even suspect that in a few hours he would be somewhere in the tropics, on a mysterious rocky island among several hundred other people who, by someone's will, became the "sowing of the Great Trey." The world of "blessed islands" at first glance looks like a fairy tale: endless ocean, eternal summer, green tropical islands with sandy beaches, forests, plains and rocks.

Will the human enclave stand up to those who consider themselves masters here?
