La fórmula preferida del profesor

A single mother goes to work as a maid in the house of an old and reclusive math teacher. However, he is not just any teacher: he was once a renowned mathematician but, after a tragic accident, he only remembers what happened in the last eighty minutes. Although he remains passionate about numbers and solving math problems, he must write important things on post-its to review every day, including the identity of those around him; a situation that makes him very vulnerable. However, the professor will gradually accept in his life the irruption of the assistant and her son, Root, ten years old, with whom he shares a passion: baseball. Little by little, a beautiful relationship based on affection and the transmission of knowledge will be forged between the three. A novel that restores faith in the human soul.
