(AP) SAN DIEGO - The bestselling author of self-help book "The Dark Side of the Light Chasers" has died in San Diego. Debbie Ford was 57.
A family spokeswoman says Ford died Sunday in her home after a long battle with cancer.
"The Dark Side of the Light Chasers" spawned a self-help enterprise for Ford. The 1998 book aimed to help readers overcome their darker side.
Her sister, Arielle, said in a statement that the author wanted to help people break free from their emotional baggage and fear.
Ford wrote eight more books, led workshops and hosted TV and radio shows related to that topic. She often shared her battle with drug addiction, divorce and other personal struggles in her work.
She is also survived by her mother, son and brother.
