Mara had never believed that a birthday could explain a person’s life. Numbers were numbers, and stars were beautiful objects in the sky, nothing more. Yet her grandmother had always insisted that Mara’s unusual birthday meant something. She was born on July 7, a date her grandmother called “a mirror of intuition.” As a child, Mara laughed whenever she heard it. But as she grew older, she noticed strange patterns. She could often sense when someone was hiding sadness, solve problems before others saw them coming, and remain surprisingly calm when everyone around her panicked.

On her thirty-fifth birthday, Mara’s grandmother gave her an old notebook filled with handwritten notes about birthdays, numbers, and personality traits. Most of it seemed like harmless superstition. Then Mara reached a page marked with her own birth date. Beneath the date was a sentence that made her stop reading. It claimed that people born on July 7 often possessed an unusual ability to recognize truths others overlooked. Mara smiled at the coincidence—until she turned the page and discovered something written there about an event that had not happened yet.
