Domscheit-Berg is about to publish a book it is announced Monday Feb. 7, 2011, giving his insider account about secret spilling website WikiLeaks, entitled "Inside WikiLeaks: My Time with Julian Assange at the World's Most Dangerous Website". Daniel Domscheit-Berg is the former spokesman for WikiLeaks, but left the site dramatically in September 2010 because of a differences of opinion with founder Julian Assange.

BERLIN — A tell-all book by a former WikiLeaks insider casts founder Julian Assange as an "emperor" who has become just the kind of public figure he is trying to expose.

Daniel Domscheit-Berg, the former WikiLeaks spokesman who left the website after a bitter dispute with Assange, writes about his euphoria at its spectacular rise and his disillusionment with a leader he describes as delusional and power-crazed.

The Associated Press reviewed a German-language copy of "Inside WikiLeaks: My Time with Julian Assange at the World's Most Dangerous Website" ahead of its release Friday in 16 countries.

Domscheit-Berg writes that WikiLeaks "turned pale computer geeks ... into public figures, who put fear into politicians, CEOS and military chiefs around the world."
