In 2975, the orphan Yatima is grown from a randomly mutated digital mind seed in the conceptory of Konishi polis. Yatima explores the Coalition of Polises, the network of computers where most life in the solar system now resides, and joins a friend, Inoshiro, to borrow an abandoned robot body and meet a thriving community of “fleshers” in the enclave of Atlanta.

Twenty-one years later, news arrives from a lunar observatory: gravitational waves from Lac G-1, a nearby pair of neutron stars, show that the Earth is about to be bathed in a gamma-ray flash created by the stars’ collision — an event that was not expected to take place for seven million years. Yatima and Inoshiro return to Atlanta to try to warn the fleshers, but meet suspicion and disbelief. Some lives are saved, but the Earth is ravaged.

In the aftermath of the disaster, the survivors resolve to …

In the aftermath of the disaster, the survivors resolve to discover the cause of the neutron stars’ premature collision, and they launch a thousand polises into interstellar space in search of answers. This diaspora eventually reaches a planet subtly transformed to encode a message from an older group of travellers: a greater danger than Lac G-1 is imminent, and the only escape route leads beyond the visible universe.

Very creative hard scifi

4 stars

A good but demanding read with great concepts for science fiction, but at times it does feel like the author tied several great short stories into one trench coat novel. Mind you, that's not a bad thing, just something to consider.

The first chapter can be seen as its own small and can be read on the authors blog, which i highly recommend! It sets the tone of the story pretty well by introducing a level of "techno-babble" that will be present at other parts of the book. You have the choice to read it and attempt to fully comprehend it or skim through it with the necessary understanding to catch the intent. If you want to understand the techno-babble or broaden your understanding, the author even supplies visual guides and very short explanations on his website, easily findable from the link for the first chapter. www.gregegan.net/DIASPORA/01/Orphanogenesis.html

Science-fiction with emphasis on the science

4 stars

Content warning Spoilers

Themes revolve around the meaning of life for individuals, which resonated with me. The book is really heavy on the technobabble.

the first half may have stretched me too far, wonderful

4 stars

Similar questions of identity and purpose as Permutation City, again that satisfying hard sharp didacticism, a broader galactic exploration scope for minds to weigh their decisions, but didn't resolve nearly as clearly for me.

SciFi can't get harder than this

No rating

I've seen it described as "diamond-hard SciFi", it might even be an understatement. It starts off being confusingly abstract. After ~15% it gets more coherent, slightly more corporeal, though never entirely so.

Even through its abstract and detached universe, it revolves around modern issues of reality, subjectivity of perception and even memetic reality bubbles.

There's a lot to get from this, provided you can keep your mind clear enough to absorb the weirdness of it all.
