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!
Another deep time book that I really enjoyed, also by Alastair Reynolds, is House of Suns
House of Suns is a fantastic read. You should also look at his shorts in Diamond Dogs and Turquoise Days.
Another fantastic short story is The Sleepover. Most of humanity is in hibernation and is being haunted by ethereal lovecraftian entities.
Turquoise Days was the first short story I read by him, and I think it could make a fun movie.
Loved those! Super weird and interesting.
Far out I love that book. Would love a return to that universe one day
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.
