On October 4, 1975, Boone married writer Dan O'Neill, in a ceremony officiated by Jack Hayford, founding pastor of the Church on the Way, in Van Nuys, California.
[citation needed] Boone came to public attention after the death of her friend, pop singer Karen Carpenter, who died in 1983 from complications arising from anorexia nervosa.
They had met in 1982 while Carpenter was attending resident therapy in New York City with psychotherapist Steven Levenkron.
Later that year, she published Starving for Attention about her recovery and life as a former sufferer of anorexia.
[1][2] They later wrote a follow-up book Living on the Border of Disorder: How to Cope with an Addictive Person.
