Author Joanne Greenberg has never been one to rest on her laurels. In 1964, her second book, the critically acclaimed “I Never Promised You a Rose Garden,” was published and sold millions of copies. The semi-autobiographical novel tells the story of a 16-year-old girl diagnosed with schizophrenia who creates an entire world inside her head as a way to retreat from the reality that she lives in an institution. The book brought Greenberg, who was also diagnosed with schizophrenia at an early age, international renown.
