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 bestselling 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, from its Cold War inception in 1958 to the present.

This is the book on DARPA -- a compelling narrative about this clandestine intersection of science and the American military and the often frightening results.
