I was listening to a science and futurism with Isaac Arthur episode about deep time and cryo ships and the book Pushing Ice by Alistair Reynolds was recommended and it sounded interesting so I gave it a read and Lord it was a really good book.

Edit: Just finished house of suns. Whoa!
I’m going to have to try to go through House of Suns again. If I remember correctly, I started to try to read it and was put off by the political world environment building or whatever. But I’ll have to give it another shot.
