The story of Alexei Gurov is a rapid rise from an outstanding engineer to the head of secret space programs. But a decisive discovery awaits him far beyond Earth: deep in space he encounters a mysterious “Something” that can put an end to his fate and demand a final decision—to keep the human inside him or disappear into the boundless universe and become part of the incomprehensible.
A moment arrives in his life that overturns everything: thrown into unexpected circumstances, Gurov has to start over. He moves from working on a breakthrough interstellar engine and taking part in risky expeditions to creating means against extraterrestrial illnesses and managing the most closed-door research. There are more and more discoveries, but the main test is still ahead—an encounter with a mysterious entity offering a choice with no right to compromise: remain human or dissolve in limitless cosmic space.
