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 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.
