I have been trying to put into words how I feel about this novel by Greg Egan. This novel leans very far into the "hard sci-fi" side of the spectrum and it isn't for everyone. Egan is a mathematician and a software engineer and those areas of expertise are relied on heavily to craft the world we inhabit in Diaspora. I have read this twice now, both times enjoying the technical masterpiece of Egan's world. The beginning is tough to read, it is slow and extremely verbose. There's no hand holding in the conceptual world you have been thrown into. If you are having trouble, the Wikipedia page is helpful to lean on and the glossary in the back of the book is a must to reference in the earlier chapters. As you get the hang of the world though, the story just flows forward. I enjoyed the pacing and characters journeys as well as the general theme of the novel. Highly recommended if you enjoy a technical and dense sci-fi novel.
The first of his books that I read. They are all mind blowing on their own ways. Not always easy reads, but super creative every time.
