About the book: year / Flights to the stars to which the cosmonauts went on relativistic spaceships are prohibited. New worlds are being discovered and explored, but those few dozen stars to which daring and fearless people have gone are untouchable. Only those who have committed the act of paying the price without returning to their era and long years of flight - only they have the right to be the first to set foot on the planets of those stars. Humanity has grown from circumstances that forced such heroism, but the honor of the pioneers will be preserved.
