Martha Wells - The Murderbot Diaries
Alastair Reynolds - Revelation Space, House of Suns, Slow Bullets, Poseidon's Wake trilogy
Joseph Heller - Catch 22
Almost anything from Philip K. Dick
Edit: Anything from Martha Wells is generally a good read. I really enjoy her style and world building. Besides, who doesn't like reading about a murderbot.
Same goes for Alastair Reynods, Revelation Space is a good space opera to chew through. I have yet to finish the Poseidon's Wake trilogy, but the first book was pretty good.
Catch 22 is a classic, same goes for most everything written by Philip K. Dick.
