I have some interest in the topic (thanks to Arraycast and Conor Hoekstra) and bought to Mock a Mockingbird by Raymond Smullyan, however it is still a bit too involved for my small brain.
On the other hand, I am very much enjoying How to Bake Pi by Eugenia Cheng, which is a few levels down in difficulty.
