If Javier Castillo (Mijas, 1987) regrets anything, it's not having believed in himself sooner enough to dedicate himself to literature. The author of best-selling titles such as The day sanity was lost (Sum of Letters, 2017) and The Snow Girl (Suma de Letras, 2020) vividly recalls the open house at the University of Málaga, when he decided to study business administration. "The guy from the university was friendly. He told me the degree had many career paths and that I would finish it in three years. I remember saying, 'Okay, that's exactly it.' Now I regret it, because I was a kid who loved to read and write, but at that time life caught up with me and I had to earn a living." Castillo, the son of a bricklayer and a cleaning woman, pursued a career as a financial advisor until he could no longer resist the urge to publish a novel.
