Daemon by Daniel Suarez
My rating: 5 of 5 stars
I saw a friend of mine had recommended this book and I had to check it out. Its mixture of IT security, philosophy, gaming, mobile technology, economics and intrigue makes for a very engrossing read that mashes up all sorts of disparate ideas into a very exciting plot.
The only downside I can find is a certain ignorance of Hispanic culture and Spanish spelling where relevant, which struck me as a little odd. Still,I cannot recommend it enough.
