The first book will come out in 2010. Bushnell, in a statement issued by her publisher, said, "Carrie in high school did not follow the crowd - she led it. It was there that she began observing and commenting on the social scene."
Bushnell's adventures of Carrie and her Manhattan pals were adapted into the hit HBO series starring Sarah Jessica Parker and a feature film that came out this year. Her fifth novel, "One Fifth Avenue," is coming out this month.
