Ask HN: Top inspiring books on crucial CS ideas?

I'm not looking for textbooks or best education materials per se, but rather for thought provoking and inspiring reading on computer science topics.

What books you find the most brilliant, inspiring and explaining the core CS ideas, data structures, algorithms?

For any level of readers, just your personal best two.

For example, I find this book amazing for beginners: https://www.amazon.com/Code-Language-Computer-Hardware-Software/dp/0735611319

And this one of the same author for more prepared reader: https://www.amazon.com/Annotated-Turing-Through-Historic-Computability/dp/0470229055/
