I have read Daemon, Freedom and Kill Decision so far. A thing I noticed with Suarez' books is that they very much remind me of the two books of Dan Brown that I've read, yet not having to cringe hard at every scene that involves technology makes them infinitely more readable to me. The settings and plot with both are ludicrous at times, but yet Suarez manages to put some interesting ideas in.
I got a similar vibe off of Stephenson's Snow Crash.
By the way: I'm not the only one for whom Sobel's bio screamed "John Carmack" from the first page he's mentioned, am I?
It's not a sequel but has some common threads.
