Ana Ballabriga and David Zaplana ran into one another for the first time in Valencia when he was studying engineering and she was a student of psychology. Their shared passion for the art of storytelling inspired them to spin the tale of their first novel, After the Cartagena Sun. A few years later they also tried their hands at video production, with results that inspired them to establish their own firm, ADN Visual, for which they've received several prizes for short features and documentaries. Ana and David are also the authors of Gothic Morbid, Switched in Time, and The Dark Circus, which won the Amazon Indie Prize in 2016.

Both live in Cartagena, Spain. They're busy with work, writing, and taking care of their two children.
