Death With Dignity: Coping With Loss In Prison With Dr. Danica Hubbard

Marshall, John (January 26, 1980). "The Scientology Papers: The hidden Hubbard". Toronto: Globe and Mail

Dr. Hubbard opens her heart to share with us a beautifully written, touching, informative, and brutally honest book about the intricacies of having a father who was a sexual predator. This is a sensitive and delicate subject that is seldom explored. It is a testament to Dr. Hubbard that she has the courage and willingness to share her journey with us. Accompanied by an article in Astounding's May 1950 issue, Dianetics: The Modern Science of Mental Health was released on May 9. [99] Although Dianetics was poorly received by the press and the scientific and medical professions, the book was an immediate commercial success and sparked "a nationwide cult of incredible proportions". [100] [101] Five hundred Dianetic auditing groups were set up across the United States, [100] and Hubbard established the "Hubbard Dianetic Research Foundation". [102] Financial controls were lax, and Hubbard himself took large sums with no explanation of what he was doing with it. [103]Sonnenschein, Allan (June 1983). "Scientology Through the Eyes of L.
