Nanotechnology, Megaplumes, and Extraterrestrials

Dan Brown has written three novels full of intrigue, secret plots, and high technology. His new book, "Deception Point," starts with the discovery of proof of life on other planets, and that sparks a high-stakes battle for power. Dan's books are meant to entertain and also make you think about some important 21st century issues. He says half the fun of writing the books is doing the research. www.danbrown.com
