[2] Serrano, who made several trips around Latin America throughout her life, left written works such as Maravillas americanas and América y sus mujeres in relation to her stay in the American continent.

Despite the unknown details of the author, it is known for certain that she lived in a privileged family and was endowed with a refined culture and an intellectual environment from her youth.

In 1852, Serrano fled to Paris in exile, followed by her lover, José Zorrilla, who called her "Leila" in his verses, and with whom she had a daughter Margarita Aurora, who died prematurely at the age of four.

[7] Serrano's stay in Paris was notable as she would rub shoulders with great personalities and French romantic writers, such as Alphonse de Lamartine and Alexandre Dumas.

In 1857, during her stay in Paris, she founded and directed, until 1860, the women's fashion magazine La Caprichosa, which was very successful both in Spain and throughout Latin America.

The scenes of the life of the Indians, described graphically; the discoveries and conquest, the battles, the heroics of the Spanish and the indigenous, the tenacious and just struggle of the sons of the New World against the invaders, alienated me to the point of forgetting everything that was not reading, giving up walks and others".

Thanks to this, she became an advisor to rulers, such as the Mexican president, Porfirio Díaz, and an official historian of countries such as Venezuela or Mexico, as well as the most widely disseminated author in Latin American schools.

[4] She also increased her journalistic activity, especially in Barcelona,[5] where she settled in the late 1880s and early 1890s to carry out commercial projects with Latin America.

[7] Above all, Serrano was the champion of Spanish-speaking women of letters: for years, she was rescuing news about the life and work of numerous contemporary writers, but also of prominent philanthropists, artists or forgotten heroines.
