I've been listening to the "3 Body Problem" trilogy by Cixin Liu. I'd highly recommend it because not only is it some mind blowing sci-fi, but it also contains one of the most interesting solutions to the Fermi paradox that I've ever seen. I don't want to give anything away because the books are a real treat if you're like me, but the explanation is based on game theory and actually makes a ton of sense.

Highly recommended.
