The Invisible Guardian

After the accidental discovery of a young murdered girl on the banks of a narrow stream deep into the impregnable forests of Elizondo, Amaia Salazar, the female inspector who leads the investigation, returns hesitantly to her hometown where she swore never to return. Inevitably, as Amaia explores a seemingly endless string of horrific ritualistic killings which enmesh the case with the mythical Basque lore, at the same time, her secret and still unhealed wounds of the past open, demanding resolution. Could the answer be hiding in the heart of the gloomy and thick woods?
