I like Crichton fine, even though I dislike his politics. I skipped Jurassic Park and Disclosure because I had already seen them ruined by Hollywood, but in general he’s a capable storyteller and a smart man. This was one of those stories where something secret is going on at a remote lab in the middle of the desert that has the potential to ruin life as we know it. It reminded me a lot of Greg Bear’s Blood Music except without the truly terrible outcome. Lots of nanotechnology that you know Crichton did some background research on, and a lot of twists and turns on the way to figuring out what the heck is really happening. This book held my interest without keeping me up at night.
