Paul Pen burst onto the literary scene with El Notice, a work that took place in Villanueva de la Cañada. His works have been translated into English, German, Italian, Russian, and Turkish.

Two of them have made the leap to the screen: El Aviso, by Daniel Calparsoro, with Belén Rueda and Raúl Arévalo, and La casa entre los cactus, by Carlota González-Adrio, with Daniel Grao and Ariadna Gil.
