Alejandra Costamagna recalls that her first approach to writing was through journal entries that she began to make irregularly from age 10.

There, Professor Guillermo Peréz "recommended her to read Neruda, Mistral, Shakespeare, Chekhov, and Crime and Punishment by Dostoyevsky, a book which still marks her writing today."

[1] Alejandra studied journalism at Universidad Diego Portales and frequented the workshops of Guillermo Blanco, Pía Barros, Carlos Cerda, and Antonio Skármeta.

These are Lina Meruane and Alejandra Costamagna, followed by Nona Fernández and by five or six young women armed with all the implements of good literature.In 2000 her first book of short stories appeared, Malas noches.

In El Mercurio, Rodrigo Pinto compared this "calling to purify and clean her texts" with that of José Santos González Vera, who used to republish his works with the warning "corrected and diminished edition", but stressed that in Costamagna it acquired a different and even more radical expression.

[6] Her works have been translated into several languages (Italian, French, Danish, Korean) and have been honored with several awards, including the Altazor (2006) and the Anna Seghers-Preis (2008) for the best Latin American author of the year.

[4] Nowadays, Alejandra Costamagna is still a writer and one of her last works is called El sistema del tacto,[7] published in 2018.
