"The Secret of Congaree Swamp"
Siblings Maya and Ethan navigated their wooden kayak through the dark, mirror-like waters of Congaree Swamp in South Carolina. Towering bald cypress trees rose from the water like ancient wooden giant sentinels, their wide knees sticking out above the murky surface. As the afternoon light faded, a strange splashing sound echoed near the bank, and a thick mist rolled over the water.
Ten-year-old Ethan froze, gripping his paddle tightly. "Maya, maybe we should turn back," he whispered, his voice trembling. "What if we're lost?"
Fourteen-year-old Maya paused, looking at her compass and checking the marked trail tags on the cypress trunks. She felt a surge of unease herself, but she knew showing fear would make her brother panic. "Look at the yellow ribbon on that trunk, Ethan," Maya said calmly, pointing ahead. "That's marker twelve. We're right on course. Let me show you how to read the compass bearings so we can lead the way together."
Ethan took a deep breath, looked at the compass face, and nodded. Working together, they paddled smoothly toward the park landing as the first stars appeared.
