Lila loves summer nights watching fireflies blink over her backyard. One evening, she notices their flashes are not random. They form patterns like lines and curves, as if drawing a secret map in the air. She calls her best friend Mateo, and together they follow the glowing trail into the moonlit woods, crossing muddy dips and climbing over fallen logs while the fireflies guide them like tiny lanterns. At the end of the path, they reach an ancient oak tree with a hollow trunk filled with dusty glass jars. Inside the jars are folded notes and small keepsakes left by children decades ago, sharing brave moments, worries, and kindness for the next finder. Lila and Mateo realize the real treasure is not something to keep, but a tradition to protect. They add their own jar with an encouraging message, then return home carrying a new kind of courage and the promise to leave a little light behind for someone else.
