Things to Make and Do in the Fourth Dimension by Matt Parker is a fun, accessible, and fascinating explanation of how math can be a big game. The Annotated Turing by Charles Petzold really is great. It comes up a lot on this website but it was a great follow up, a good bridge from the fun almost hack-y math to a more "serious" approach. This led me to: Computability and Logic by George S Boolos. A standard textbook in universities across North America (and maybe further?). In the end I didn't become a mathematician. I hardly use advanced math compared to many other engineers and scientists but the ideas have stuck with me for years, and I think my life is richer for knowing them
