Fosca

"Fosca" is an 1869 Italian language novel by Iginio Ugo Tarchetti, initially published in serial form. "Fosca" served as the basis for Ettore Scola's 1981 film "Passione d'amore" as well as Stephen Sondheim's 1994 stage musical "Passion". Due to the success of the stage adaptation, an English translation by Lawrence Venuti was published in 1994 as "Passion: A Novel" (Mercury House).
