I read a shit-ton of science fiction books and the main reason is that I find them useful as a prelude in doing further research for various scientific issues that I'm unaware of. That and the fact that they're fun.
Sure, here are the best ones I've read this last year (not all of them are published in 2020 though).
We are legion - D. Taylor. A four book series, haven't read the rest of the books.
Children of time - A. Tchaikovsky
The Unicorn Project - G. Kim. This would be especially interesting for the HN crowd. It's not sf per se, rather more than contemporary fiction, but the main theme is about programming and politics in a big corporation. Quite original and a lot of fun.
Agency - W. Gibson
The space between worlds - M. Johnson
To sleep in a sea of stars - C. Paolini
The algebraist - I. Banks
Hope you'll find something to your liking. Happy new year.
