The Museum of Unclaimed Luck (en Inglés) - Carrie Ray

The Museum of Unclaimed Luck follows 14-year-old Leo, who takes a boring summer job in a dusty basement archives. He quickly learns it's not a regular museum; it houses the physical objects connected to "missed" moments of fortune-a winning raffle ticket left in a pocket, a coin that should have been found, a letter that got lost in the mail. Leo discovers he has the rare ability to "activate" these items and return the luck to the person it was meant for. But the universe demands a balance: every time he grants a piece of "Unclaimed Luck," he must personally absorb a piece of "Residual Misfortune." Leo and his friends must decide if changing people's lives is worth the cost of their own bad luck.
