Ask HN: The book you always wanted to read but never had time or motivation for?

What is the book you always wanted to read but never had time or motivation for?

Three answers are allowed, one is to look smart (eg: "The Count of Monte Cristo"), one is for the title you are a little ashamed of (eg: "The Neuromancer"), one is for a tech book (eg: "Lions' Commentary on Unix").

Thanks for sharing your thoughts!
