The world-building is really interesting, probably the best aspect of the novel is how Chu creates an attractive mix of dystopia, space-opera and time travel. The protagonist is James, a Chronmen, a time traveler with a mission to move to certain points in history to rescue resources of the past without altering the flow of time.

The story takes us to the XXIV century and presents a humanity that has been able to conquer and colonize many of the planets and moons of the solar system, but with a polluted Earth without resources and with much of the population with health and alimentation problems. It is understandable, because the novel clearly presents a cinematographic style, which at times is a virtue (the novel has a lot of rhythm and it's very entertaining), and others a defect (because it not deepens in many interesting aspects of the plot).
