This is a title of a major novel by American writer Jacqueline Susann, published in 1966. The "dolls" within the title is a slang term for downers, barbiturates used as sleep aids.

Valley of the Dolls was an instant success when it was first published. Since then it has sold more than 30 million copies. As the first roman à clef by a female author to achieve this level of sales in America, it led the way for other authors such as Jackie Collins to depict the private lives of the real-life rich and famous under a veneer of fiction.
