project Hail Mary was fantastic. I just finished "The Postman" by David Brin and "Dark Angel" by John Sandford. I really enjoyed "Powersat" and its sequals by David Brin too.
Edit: i also recently read "Radicalized" by Cory Doctorow because it contained the novella "unauthorized Bread"
I just finished Radicalized too! Just started Walkaway by the same author, might be enjoying it even more. Doctorow and Kim Stanley Robinson are probably my favorite authors this year, I can't stop reading them.
