Luna received a BA in Hispanic Philology from the Universidad Autónoma of Madrid and pursued graduate studies at the same university specializing in the literature of Spanish Civil War.

As a result of a trip to Lima in 1987 for the documentary on César Vallejo Acaba de pasar el que vendrá, she started to be interested in screenwriting.

She took courses taught by José Luis Borau, Manuel Matji, Lola Salvador, Joaquín Jordá y Agustín Díaz Yanes, and in 1997 she studied screenwriting at the Universidad Politécnica de Cataluña.

Moreover she participated in the feminist collective film project Yo decido: El tren de la libertad (2014).

In 2017, the socially committed cabaret For Sale, a comedy on the life of Maria Cumplido in times of crisis, premiered at Luchana Theater.

She offered workshops at the Fundación Carolina, at the Laboratorio de Oaxaca (Mexico) sponsored by Sundance, in Colombia, and in Brazil.
