Ernest Prunera (Sabadell, 1973) wanted to write a biography of Guifré el Pilós, but when he set about it he found that the information about that period, the second half of the 9th century, was "scarce and uncertain", so he changed his mind and allowed fiction into the project, which became one. When the storm passes (Column) imagines the childhood of Guifré el Pilós, when he was still a child without honors or glory. The book features Marwan, a young homosexual Muslim who acts as Guifré's tutor, and is the winner of the 29th Néstor Luján Historical Novel Award. "It's a very well-written work about a complex period in history," says Maria Carme Roca, a member of the award's jury, adding that one of the book's strengths is "how it explores a rarely fictionalized historical moment, transforming the lack of documentation into a freedom to create stories."
