Hidden Truth: Forbidden Knowledge

Hidden Truth: Forbidden Knowledge (Crossing Point, 2006) is Steven Greer's memoir of the Disclosure Project years and his spiritual philosophy: his accounts of meetings with officials and insiders, of what he says he learned about secret programmes, and his view that contact with extraterrestrial civilisations is bound up with expanded consciousness. Like his other books, it is his own testimony and belief, without independent corroboration.
