Sandra Alonso was born in Zamora on April 9, 1993. A teacher by vocation, after taking some subjects on children's literature, she was bewitched by the magic of stories. In 2015, she created the blog "Mis cuentos infantiles" ("My children's stories"), where she talks about books from all over the planet to teachers, families and, in short, to anyone who loves children's literature. In late 2018 she took the leap and became an author, discovering at that precise moment her true passion: writing. In the summer of 2020, she went a little further and opened in her hometown her own bookstore specialized in children's literature, a space in which she intends to "live off stories."
