The end of eternity. Azimov A.

Having reached a certain level of development, science solves the task of traveling in time using the enormous energy of the explosion of supernova. Humanity creates a structure, calling it “eternity”, which includes specially trained and selected people from different centuries, which gave a vow of celibacy. The task of the “eternity”, at the head of which the council of time is, is to adjust the fate of mankind, which in its path is always sliding to self -destruction. The harsh and ascetic laws of "eternity" are debugged and never fail. But once the young and brilliant technician Harlan, having made one of the movements in time, falls in love with the beautiful girl Nois from the other century. Love circles his head, hesitates his foundations. Harlan faces a choice - duty and submission to the law or personal happiness? His decision can lead to time paradoxes and even the disappearance of the “eternity” itself.
