In a very small town in rural Argentina there is a magical house. No one has lived in the house for almost as long as anyone can remember. But once a year, at midnight, the house turns blue and twenty-four hours later it turns back to white again. Twelve-year-old Cintia lives with her father. Her mother left town when Cintia was a little girl and she can hardly remember her. But Cintia finds great comfort in her grandmother’s house where she is fed delicious food, told stories and is loved. Cintia father is a very angry man and his anger is often turned against her. Cintia also finds refuge in the Little Blue House. She is drawn there repeatedly even though her father has told her not to go, and the town Mayor, forbids anyone from visiting the place without paying. As the time approaches for the annual transformation of the house more mysteries crop up. Cintia and her grandmother must come to grips with what Cintia’s father’s actions. The Mayor’s plans must be confronted and an old bookseller needs to find a way to save what is most important. And what about the rumors of buried treasure?
