For many years, heartache prevented Nahid Rachlin from turning her sharp novelist's eye inward: to tell the story of how her own life diverged from that of her closest confidante and beloved sister, Pari. Growing up in Iran, both refused to accept traditional Muslim mores and dreamed of careers in literature and on the stage. Their lives changed abruptly when Pari was coerced by their father into marrying a wealthy and cruel suitor. Nahid narrowly avoided a similar fate and instead negotiated with him to pursue her studies in America. When Nahid received the unsettling and mysterious news that Pari had died after falling down a flight of stairs, she travelled back to Iran - now under the Islamic regime - to find out what happened to her truest friend, confront her past and evaluate what the future holds for the heartbroken in a tale of crushing sorrow, sisterhood and, ultimately, hope.
