Unabridged Audiobook
Proper hard sci-fi with a great story too. Gripping throughout and it's really 3 books in one. It was recommended to me strongly and I was not disappointed, if plot holes and scientific inaccuracies annoy you, and you want a good story then reeeaad! Also a potential existential risk planning that longtermism philosophy covers so worth a read if you're into that too.
