In the absence of witty remarks about these two books by the undisputed master of the techno-thriller, I can just brief you on the contents (Prey is about a swarm of nano-robots that develops a hive mind and really gets under people's skins, and Timeline is about time travelling to the Dark Ages), and use the opportunity to point out that I have read Jurassic Park, as well as owned and worn a Jurassic Park T-shirt, well before the movie was released.
