In this delightful read, Maudlin goes through an array of topics revolving around non-locality, relativity, and the mathematics involved. However, although I didn't find any "new" ideas in the text, I was amazed at how quickly & clearly he explained the said topics. Without exaggerating, in 80 pages of this book I attained what had taken me an entire stack of now useless books on quantum physics (particularly Bell's theorem), relativity, linear algebra, and philosophy(don't read Philosophy of Physics by Lange, you'll get it all out of this)
Anyone who has a prior introduction to Quantum theory will love this. I'd suggest Quantum Reality by Herbert, But there are lots of good ones out there.
