The morning of the publication of "Alas de hierro", on February 21, thousands of readers queued up to get their copy, a passion not seen among the young public since the Harry Potter saga.
An extraordinary reception by readers, booksellers, and the media: the Empyrean series, with only two volumes published and 400,000 copies sold in our country, has already become the biggest publishing phenomenon of recent years. “Alas de hierro” has beaten the sales record in a first week since Stieg Larsson or Harry Potter.
