For more than 40 years, the US government has researched extrasensory perception, using it in attempts to locate hostages, fugitives, secret bases, and downed fighter jets, to divine other nations' secrets, and even to predict future threats to national security. The intelligence agencies and military services involved include CIA, DIA, NSA, DEA, the navy, air force, and army - and even the Joint Chiefs of Staff. Now, for the first time, New York Times best-selling author Annie Jacobsen tells the story of these radical, controversial programs.

Discover the definitive history of DARPA, the Defense Advanced Research Project Agency, in this Pulitzer Prize finalist from the author of the New York Times best seller Area 51. No one has ever written the history of the Defense Department's most secret, most powerful, and most controversial military science R&D agency. In the first-ever history about the organization, New York Times best-selling author Annie Jacobsen draws on inside sources, exclusive interviews, private documents, and declassified memos to paint a picture of DARPA, or "the Pentagon's brain".

It is the most famous military installation in the world. And it doesn't exist. Located a mere s75 miles outside of Las Vegas in Nevada's desert, the base has never been acknowledged by the US government - but Area 51 has captivated imaginations for decades. Annie Jacobsen had exclusive access to 19 men who served the base proudly and secretly for decades and are now aged 75-92, and unprecedented access to 55 additional military and intelligence personnel, scientists, pilots, and engineers linked to the secret base, 32 of whom lived and worked there for extended periods.

This is a story that starts off close and goes very big. The initial part of the story might sound familiar at first: it is about a platoon of mostly 19-year-old boys sent to Afghanistan, and an experience that ends abruptly in catastrophe. Their part of the story folds into the next: inexorably linked to those soldiers and never comprehensively reported before is the US Department of Defense’s quest to build the world’s most powerful biometrics database, with the ability to identify, monitor, catalog, and police people all over the world.
