The night notebook
After being the most promising of her generation, Spanish astronomer Estrella Noval feels stuck in her dull position at a research center in Madrid. But her monotonous world is shaken when she learns that a young scientist with whom she had a love affair has been found dead in London.
At that moment, a strange message comes into her hands, which she must decipher and which will end up dragging her into a race against time with the help of Tobías Satrústegui, a detective with crude manners, in which a powerful competitor is willing to do anything to prevent her from finding answers to the questions that obsess her: What cost her former partner her life? And why is someone willing to do anything to get ahead of her?
Miguel A. Delgado bursts into the national thriller scene with this fast-paced mystery set in a centuries-old institution.
A fast-paced thriller full of science and tension starring the brilliant astrophysicist Estrella Noval and the peculiar detective Tobías Satrústegui.
