The narrative is in the first person, as Harry August recounts his first fifteen lives. Harry is one of the few kalachakra endowed with perfect memory of their past lives, so his account can be detailed. However, a kalachakra must be careful not to be specific about their origins, as this information can be used to make sure they were never born, thus deleting them permanently from the timeline. So Harry has every reason to be an unreliable narrator. The story is told in nonlinear fashion at the beginning, as Harry slides from one life to another to fill in context and motivation, and then straightens out as the battle between him and Victor gains momentum.
The story seems a little difficult to follow at first, due to the complexity of the image of time underlying the initial premise. However, the time-image is not really very complicated, as it is basically linear time with re-sets when a kalachakra dies, allowing for passage of information from the future to the past, and progressive modification of the time-line. This is something that an association of kalachakras, the Cronus Club, tries to keep to a minimum.
Victor’s accelerationism is bringing him ever closer to the Quantum Mirror, but it is also ruining the planet at an ever faster rate. Harry shares sum of Victor’s curiosity, but cannot accept the means to the end, the ecological degradation, the overweening narcissism. In a way, both are demi-gods, but Harry opposes Victor’s hubris, based on physics, with the more humble science of accounting. Both are masters of cunning and of simulation, so the end is predictably ambiguous.
