The secret survivor of an AI’s rampage must finally take an active role in the struggle for that AI’s legacy.
On an unnamed planet, artificial intelligences—who would physically interface with select humans trained as archivists—apparently used to have absolute rule over the city-states. But many of these AIs became corrupted, causing carnage and destruction. The human government of the Harbor has salvaged the spare parts of some of these dead AIs and rebuilt them as ENGINEs, mechs under human control. Sunai, a dissipated wanderer who works on salvage rigs, hides the fact that he was once an archivist to the AI Iterate Fractal and that the AI’s corruption while he was interfaced with it has made him seemingly unable to die or suffer permanent physical damage. A drunken encounter with Dr. Veyadi Lut, another former archivist, sets Sunai on a dangerous mission against the Maw, the ENGINE built from the remains of Iterate Fractal. Sunai is forced to confront his troubled past and his conflicted loyalties with old friends and lovers, navigate a complicated new relationship with Veyadi, and contend with the forces marshaled by the Harbor, the Maw, a crime syndicate, and a nameless AI that has become attached to Sunai’s mind. Readers may find themselves desperately searching for more explanatory backstory, which is only partially forthcoming. Interludes told in the second person by at least two different AIs, one of which is supposedly dead (except maybe not?), only add to the confusion. It's not always possible to tell who is narrating or experiencing various moments of the story, as consciousnesses merge and only incompletely separate. There’s definitely some important point being made about the nature of sentience, but it’s not 100% clear what that point is. An author shouldn’t have to overexplain; getting flung into the deep end and figuring out the parameters of a new universe can be a fun genre challenge. But sometimes there is just no clear path out of the pool.
Intriguing but difficult to follow.
