The bad girl - Mario Vargas Llosa

When the beautiful teenage Lily arrives in Lima in 1950, fifteen-year-old Ricardo falls instantly in love with her. She claims to be from Chile, but vanishes the moment it becomes clear that she has lied about both her name and her nationality. A decade later, now living in Paris, Ricardo falls in love with a woman named Comrade Arlette, who is incredibly similar to Lily but refuses to acknowledge that she is the same person. For his whole life, Ricardo seems doomed to keep running into 'Lily', and to keep falling in love with her. Will he ever discover who she really is?
