On an autumn day in London, the dark secrets and troubled past of Margam Mazar surface violently with tragic consequences for her pregnant daughter, Sara, and her newly orphaned nephew Saeed. Racked with guilt, Maryam is compelled to leave the safe comfort of her suburban home and mild English husband to return to Mazareh, the remote village on Iran's north-east border where her story began. There she must face her past and the memories of a life she was forced to leave behind when her  father disowned her for a sin she did not commit, in the days when she was young, headstrong and beautiful.
