Synopsis: The narrative is set at a castle in Brittany, where a man has invited a friend, who also has brought a young woman. The novel is loaded with symbols and uses narrative modes from Gothic horror literature, which it blends with Hegelian thinking and stylistic traits close to the surrealist movement, including a highly abstract plot. In his "Notice to the reader", Gracq describes the book as a "demonic version" of Richard Wagner's opera Parsifal [from Wikipedia].
