Jackie Collins, the best-selling author of dozens of steamy novels set in the boardrooms and bedrooms of Hollywood's power crowd, died on Saturday of breast cancer. She was 77. The British-born Jackie, sister of actress Joan Collins, died in Los Angeles, said her spokesman, 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.Joan, reacting to her sister's death, told People magazine that Jackie was her best friend.Earlier this month, Jackie told People she had only recently told her older sister that she had battled with breast cancer for six years."I admire how she handled this. She was a wonderful, brave and a beautiful person, and I love her," Joan told the magazine.Jackie, who wrote about characters driven by lust, power and greed, sold more than 500million copies of her books in 40 countries and has had 30 New York Times bestsellers.She followed her older sister to LA when she was a teenager. She did not only write about Hollywood, she also enjoyed great success in entertainment with several of her stories adapted for television."I'm a storyteller. I'm not a literary writer and I never pretended to be," she said.Some of her most successful novels included Hollywood Wives in 1983, about women living glamorous lives behind the scenes of the movie 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 organised crime.Jackie faced controversy during her career, writing novels so steamy that they outraged politicians from Britain to China.Her debut novel, The World is Full of Married Men, was deemed "filthy and disgusting" by author Barbara Cartland and banned in Australia.She said the book was "way before its time" with its tale of a woman who cheats on her husband and another who likes sex with married men.With her unrivalled insider's knowledge of Hollywood, she said she wrote about "real people in disguise. If anything, my characters are toned down - the truth is much more bizarre."..
