Paul Pen is a bestselling Spanish author whose four novels have been translated to many languages. The Light of the Fireflies was his first book to be translated to English, selling more than one hundred thousand copies worldwide. This book was followed by Desert Flowers and Under the Water, with which he reaffirmed his unmistakable brand of literary suspense and ability to create a deeply immersive reading experience for the mind, heart and nerves. Now, his debut novel of almost ten years ago, The Warning, is being published in English for the first time, finally offering readers around the globe the chance to read a story already adapted to the big screen in 2018. Motion pictures of The Light of the Fireflies and Desert Flowers are also in development, the latter scripted by Pen himself. In his capacity as scriptwriter, Pen is working on a forthcoming Netflix series while he writes his next novel.
