What is your favorite technical book and why?

During a call with my teammates last week, we started chatting about our favorite technical books. After confessing to my team that I still have my text book from my Computer Organization class because I loved the class so much, I had to think a little bit. I answered with The Pragmatic Programmer. The ideas and values in this book have stuck with me throughout my career and I pride myself on bringing a pragmatic lens to all the problems we solve each day.

And this got me wondering how the Community.aws community (that's you!) would answer this question, so I want to pose it to you:

My To Be Read list is a mile long, but I'm always looking to expand my brain around technical topics and find ways to get away from a computer screen. Drop your favorite technical book in the comments below and maybe you can add something new to your To Be Read list.
