Over a hundred and fifty years into their voyage, the inhabitants of a generation starship are only a decade out from the Tau Ceti star system. Despite the massive size of the ship, delicate ecological cycles have been slowly deteriorating over the decades. After arrival, more serious problems crop up with the colonisation effort. The issues are so severe that the colonists are faced with deciding whether to stay, or attempt a return to Earth. Both options are fraught with risk.
While the novel ostensibly chronicles the life of a single inhabitant, Freya, it is also fair to say that the AI running the ship is as much a protagonist. Ship, as it prefers to call itself (or is it themselves) develops over time under the ministrations of Freya’s mother Devi, and much of the novel deals with the emergence of its consciousness. Indeed, many pages are spent debating the nature of consciousness and sentience. Is Ship truly sentient? Can a purportedly sentient being even know if it is sentient?
A lot of time is also spent on the suitability attempting to colonise other star systems, or even other planets in the Solar System. Mr. Robinson’s ultimate answer to this question is rather surprising, but hopeful in its own way.
The narrative feels somewhat impersonal, as if the reader is kept at a distance from the protagonist and even the action. This seems to be a conscious choice on the part of Mr. Robinson, given that the story is told in the voice of Ship itself, even as Ship’s understanding of language and humans develops. An interesting narrative device, and finely implemented.
