I was just wondering if anyone had read any books by Greg Iles. If you haven't, you should try one. I recommend Dead Sleep. I'm reading his second newest one now footprints of God and I was up 'till 2:00 last night because I couldn't put it down. It's all about this government conspiracy to build a supercomputer that thinks like a human, kind of like HAL from 2001:space oddesy, except that in this computer you load actual human memory into a computer, which allows you to expand on that memory with other knowledge very quickly (like in the Matrix). Anyway, good author.
Also, he Da Vinci Code was another excellent book, a real page turner by Dan Brown.
