LOS ANGELES - Jackie Collins , the best-selling author of dozens of novels of Hollywood’s power crowd, died on Saturday night of breast cancer at age 77, her family said.

The British-born Collins, younger sister of actress Joan Collins, died in Los Angeles, said her spokeswoman Melody Korenbrot. “It is with tremendous sadness that we announce the death of our beautiful, dynamic and one of a kind mother, Jackie Collins , who died of breast cancer today,” the family said in a statement.

Collins, who wrote about characters driven by power and greed, sold more than 500 millions copies of her books in 40 countries and has some 30 New York Times bestsellers, according to her own website.

Collins followed her older sister to Los Angeles when she was just a teenager. She did not only write about Hollywood, she also enjoyed great success in the entertainment industry with several of her stories adapted for television.

“I’m a storyteller. I’m not a literary writer and I never pretended to be,” Collins told Reuters in 2008.

Some of her most successful novels included the 1983 “Hollywood Wives,” about women living glamorous lives behind the scenes of the industry, and the 1985 “Lucky” and 1990 “Lady Boss” from her series focused on the ravishing and ambitious character Lucky Santangelo, who was born into an organized crime family.
