the invisible girl

Aurora Ríos is invisible to almost everyone. Past events have made her isolate herself from the world and hardly socialize. At seventeen, she has no friends and is tired of the townspeople talking behind her back. One May night, her mother doesn't find her at home when she returns from work. This is unusual. Aurora is found dead the next morning in her high school's changing room, the Rubén Darío. She has a blow to the head and a compass has been left next to her body. Who is responsible for that terrible event? Julia Plaza, a classmate of the invisible girl, is obsessed with finding the answer. Her great intelligence and prodigious memory allow her to solve a Rubik's Cube in fifty seconds or be invincible playing chess. But will she be able to help her parents solve that enigma? Her mother, Aitana, is the forensic doctor for the case and her father, Miguel Ángel, is the sergeant of the Judicial Police of the Civil Guard in charge of the investigation. Julia, along with her inseparable friend Emilio, a very peculiar boy with a disturbing gaze, will try to do everything in her power to ensure that Aurora Ríos's murder does not go unpunished. Will they manage to find out who the Compass Killer is and what is behind that strange death? In this high school everyone has secrets, everyone seems guilty, everyone is a suspect.
