The Lost Daughter is a novel published by writer Elena Ferrante in 2006, in Italian (original title: La Figlia Oscura), and translated to English by Ann Goldstein in 2008. The novel was adapted to cinema in the film of the same name, in Maggie Gylenhall directorial debut, starring Olivia Colman, Jessie Buckley and Dakota Johnson.
