After his first book was translated into 10 languages and published in more than 63 countries, Javier was signed up by Penguin Random House Spain who have since published six more novels.The Snow Girl, his fourth novel, has sold more than 2 million copies in Spain and become an international phenomenon. His subsequent novels, The Soul Game and The Crystal Cuckoo, have been instant no. 1 bestsellers, and will both be adapted for the screen by Netflix.

Many books never live up to their hype but this one is an exception. The Snow Girl is a well-layered, pacy thriller that builds to a satisfying finale. Investigative journalist Miren Triggs is a lead character I hope we see more of
