Hey, if you wanna understand 1+1 all you need to read is this little beauty:
I have not read it myself, because I am stupid, but I did read a comic book about how and why it was written: https://www.amazon.com/Logicomix-search-truth-Apostolos-Doxiadis/dp/1596914521
You might enjoy the "Math Girls" series by Hiroshi Yuki: https://www.amazon.com/gp/bookseries/B00YYJYP2C
In particular, the third book does a pretty nice job covering the Peano axioms and some of Gödel's results. They don't have too much of a plot (its more math than fiction) but I would still recommend reading them in order.
Another fun one on foundations is Logicomix, its a graphic novel: https://www.amazon.com/Logicomix-search-truth-Apostolos-Doxiadis/dp/1596914521
Hofstadter's "Gödel, Escher, Bach: An Eternal Golden Braid" is another really excellent book on foundations.
James Gleick's "Chaos: Making a New Science" is really fantastic in describing both the history and content behind chaotic dynamical systems, I highly recommend it.
A book that blew my mind in high school was Manfred Schroeder's "Fractals, Chaos, Power Laws: Minutes from an Infinite Paradise"; it might be a little harder to find.
