Query: Immortal

This was my first venture into Michael Crichton works. Quite an impressive coverage of research done by the author. This book has some strong arguments of the general perceptions among the people. If you are an environmentalist and if you think you know a lot about global warming, try this book. The main characters in the book were all "immortal" and some of the actions were a little bit surreal. Generally, it's fun read and the most interesting part was the discussion of the "State of Fear".
