I personally feel that there are so many interesting true stories in mathematics and physics that I would point you towards nonfiction stuff like Fermat's Enigma by Simon Singh, the Logicomix graphic novel about Bertrand Russell, or any of the lauded biographies on Turing, Noether, Erdos, Ramanujan, Riemann, Perelman, Feynman, the list goes on and on. If you are sure you want to read some fiction, you can try the Quantum Thief series, Cixin Liu's Three Body Problem series, or the Goodreads shelf on "Math Fiction": https://www.goodreads.com/shelf/show/math-fiction https://www.goodreads.com/shelf/show/math-fiction
