She studied Geography and History at the Universidad Complutense de Madrid. She was married to the poet Luis García Montero. In 1989 she won the La Sonrisa Vertical prize with her erotic novel Las edades de Lulú, which has been translated into several languages. Bigas Luna made a movie based on this book, as did Gerardo Herrero with Malena es un nombre de tango and Juan Vicente Córdoba with El lenguaje de los balcones in his film Aunque tú no lo sepas.
As Emilie L. Bergmann said, her novel Las edades de Lulú (1989) "represented a breakthrough for eroticism in women's writing".
Her books speak about the Spanish people in the last quarter of the 20th century and the first years of the 21st century. She shows in them a great realism and an intense psychological introspection.
