I found the book "The definitive book of body language: How to read others's thoughts by their gestures" by Allan and Barbara Pease to be a great read.
The greatest show on Earth - Richard Dawkins was an excellent read.
Surely you're joking Mr Feynman by Richard p.Feynman was terrific read by a very small bit can considerred offensive or at the least dated in its outlook but if you can get past that its great!
I recently finished a book on ID called "Masters of doom" by David Kushner which I rather enjoyed as well.
I also love reading about crackers from the (mostly) 80's and I can recommend.
Cuckoo Egg by Cliff Stoll
Masters of deception
We are anonymous - Inside the hacker world of lulzsec, anonymous and the global cyber insurgency by Parmy Olson
I loved "Underground Hacking Madness and the obsession on the electronic frontier" once I got past the first 2 or 3 chapters (also it was researched by Julian Assange before wikileak and has a chapter about his hacking) An Ebook copy can be found on the authors website http://www.underground-book.net/download.php3
