Daniel Pérez Castrillón, born in Asturias in 1990, works as a bookseller, although he insists his true profession is that of a ‘professional reader’. He runs the genre literature and comics blog Boy with Letters and is a contributor to Windumanoth magazine – meaning he eats, breathes and lives genre literature. As Mangrii on social media, he shares content on science fiction, fantasy and horror, while also exploring other cultural interests such as young adult fiction, manga, television series and cinema.
