I think my favourites of his are Airframe, Congo, and Andromeda Strain.
Now, if you want real page-turners, might I recomment Preston & Child? These guys wrote Relic (butchered for the movie - Hell, they left out the very best character!) Reliquary (sequel to relic,) Cabinet of Curiosities, Thunderhead, Mount Dragon, Riptide, Ice Limit, and a couple others I haven't read yet (like Brimstone - supposed to explain a lot more about FBI Special Agent Pendergast...)
Riptide is a very interesting rendition of the old Oak Island Money Pit legend (probably the single story with the most influence on getting me to learn to read...) which should be familiar to those of you who live "Down East." Cabinet of Curiosities is a serial murder mystery with a really good twist, and Mount Dragon is a bioscience thriller.
If you haven't already, give them a go sometime... Their full proper names are Douglas Preston and Lincoln Child.
