Monuments (the Chronoliths) to the glory of military victories of a dictator, Kuin, are sent from the future. The book tells through the antihero Scott Warden, 20 years, attempts to understand and stop the inevitable arrival of the future war and the victory of Kuin. As always with Wilson, there is a great human and social dimension in the novel: Scott is a divorced father in a dark time, how the company reacts to the arrival of Kuin, fanaticism, etc ...
For this novel, I hesitate in 3 and 4 star SF history (temporal paradoxes) is smart but is not pushed into the corner. The character's life, interesting and well written, take up much space and too ratentit plot twists relative to history. Unlike Spin, newest true, Wilson did not find here the right balance between SF and chronic life.
Nevertheless, it is well written, intelligent and still above normal SF production. So good but too slow.
