Query: Probably Crichton's Best

This book, Jurassic Park, is one of Crichton's best books, if not the best of them all. Basicaly a simple story, man creates dinosaur and then loses control of dinosaur. Runs in the same vein as Frankenstein. Anyways, a really good book, the first time I read it, I finished it in a about a day and a half, I've read it four times since then, the story never gets old and is a thriller every time.
