Sweet Valley High author Francine Pascal has died at the age of 92 after a battle with cancer.

Pascal died of lymphoma at NewYork-Presbyterian Hospital in Manhattan on Sunday,her daughter Laurie Wenk-Pascal told the New York Times.

The beloved writer found global success with the hit book series about identical twins Elizabeth and Jessica Wakefield,which was formative reading for generations of young girls.

The series,set in the fictional Los Angeles suburb of Sweet Valley,debuted in 1983 and consisted of 181 books,also spawning multiple spin-offs,including Sweet Valley Twins and Sweet Valley University.

It ran for 20 years and was translated into 27 languages,selling hundreds of millions of copies worldwide.

Pascal was born in Manhattan on May 13,1932,but grew up in Queens.

She studied journalism at New York University and then worked as a freelance writer for various publications including True Confessions,Modern Screen,Cosmopolitan and Ladies’ Home Journal.

Pascal's writing career started to take off after she married her second husband John Pascal - a year after divorcing Jerome Offenberg - and the couple worked together on the 1960s soap opera The Young Marrieds.

In the 1970s she ventured into the world of young-adult novels with Hangin' Out With Cici,My First Love And Other Disasters and The Hand-Me-Down Kid,and found that teenage girls were a receptive audience for her efforts.

Pascal,in an 1988 interview with People Magazine,praised the Sweet Valley series - which sold more than 200 million copies - because it 'created readers out of non-readers'.

'These books have uncovered a whole population of young girls who were never reading,' she said of the books.

Pascal also wrote several books for adults,including a non-fiction book about the Patty Hearst trial,The Strange Case Of Patty Hearst,in 1974. She also penned adult novels Save Johanna! in 1981 and If Wishes Were Horses in 1994.

Pascal is survived by her two daughters Laurie and Susan,six grandchildren and five great-grandchildren.
