The doors of some of the world's best-hidden places and most secretive organizations have now been thrown wide open! Some of the names are Area 51, Yale's Skull and Bones, Opus Dei, the Esalen Institute. Others are more obscure, hidden by fate or purposeful deception, such as the Mount Weather Emergency Operations Center, the super-secure facility where Vice President Dick Cheney was secreted after the 9 11 attacks, and Germany's Wewelsburg Castle, which was intended to become the mythological centerpiece of the Nazi Regime. Readers can take an unprecedented look deep inside the off-the-map military installations and shadowy organizations that operate in the murkiest corners of our world.
