Query: A very entertaining read

I really liked this book. It's very well written. Better, I think, than the DaVinci Code (I think Darnton is a better writer), although the latter has a more mysterious story. I'm making the comparison because clearly the book was fashioned in some way after the success of the DaVinci Code. Both are historical fictions and touch on important figures, and they're both engaging and entertaining enough to cause an all-nighter or two.While the DaVinci Code actually makes you think -- wow, could the whole book, or at least substantial portions of it, be really true? You don't quite get that feeling here at the end. Still, the ending to the Darwin Conspiracy is fantastic and when one considers the people in question and their beliefs, there is little doubt that others like them throughout the world who've had similar beliefs were closer to the truth than the rest of the civilized world.
