The first chronolith arrived without warning. The 60-meter-high column destroyed everything around it and could neither be split nor exploded. It celebrated the victory of an unknown commander in a battle that would happen only 16 years later. The first chronolith came from the future, but it was not the last. Every year more and more of them appeared, they demolished entire cities, wreaked havoc and overthrew states, proclaiming the power of a ruler whose existence no one knew, using technologies whose secret no scientist in the world could unravel. Scott Worden, who became a witness the emergence of the first chronolith, against his will, he finds himself in the very center of the study of this mysterious phenomenon, in the epicenter of the battle with the inevitable future. But how can we prevent something that has already happened? And is this possible?
