Former Sea Org member Dan Koon worked in the compilations unit of Scientology (RTRC) where Hubbard's writings were turned into official Scientology books, lectures, and publications. Many of these products were sold to Scientologists and the public and thus represented a significant income stream for the Church. Accordingly, David Miscavige micromanaged compilations and Dan worked closely with Miscavige. After leaving the Sea Org, Dan Koon later helped Ron Miscavige Sr. to write his New York Times bestselling book -- Ruthless: Scientology, My Son David Miscavige, and Me.
