El libro negro de las horas

Someone who's been dead forty years can't be kidnapped and certainly can't bleed. Vitoria, 2022. Former inspector Unai López de Ayala -alias Kraken- receives an anonymous call that will change what he thinks he knows about his family past: he has one week to find the legendary Black Book of Hours, an exclusive bibliographical jewel, if not, his mother, who has rested in the cemetery for decades, will die. How is this possible? A race against the clock between Vitoria and the Madrid of bibliophiles to trace the most important criminal profile of his life, one capable of changing the past, forever.
