Ever wonder what goes on at America's most secretive military base, Area 51?

Investigative reporter/contributing editor at Los Angeles Times magazine Annie Jacobsen did. She talked about her new book, "Area 51: An Uncensored History of America's Top Secret Military Base" last night with Jon Stewart on "The Daily Show."

For her book, she interviewed 71 men with direct access to the base, 32 of whom lived and worked there. Though she debunks the alien myths that have been associated with Area 51, Stewart noted, "What is in the book is almost more disturbing than the idea that there was an alien visitation."

Jacobsen relayed some particularly shocking facts in the interview, but the book itself contains even more. Stewart ended the interview encouraging people to buy the book: "Read it from page 1. It will blow your mind." And read the author's own words in an exclusive HuffPostBooks slideshow here.
