Reamde is brilliant. Just finished Seveneve. Great story and a rattling good tale but some of the science didn't quite ring true to me. Well worth a read though and whilst not Stephenson's finest, not nearly as disastrous as some of the reviews would have you believe.
And storming my way through Reamde by Neal Stephenson at the moment. its a proper page turner, which at >1000 pages is a good thing
