In the groundbreaking tradition of DK's New York Times bestseller Pick Me Up, this book uses the same irreverent style to explore all the things THEY don't want you know about. From the Mona Lisa's hidden past to the history of Area 51, Do Not Open explores lost worlds, unravels secret codes, and lets readers step through the looking glass to see if they can handle the truth!
