At first, Joaquim thought the sound was coming from the reeds. It was still too dark to see much of the river, and the narrow stretch of water ahead of him looked almost black under the last of the night sky. He had gone out before sunrise like he always did, easing his little wooden boat through one of the quieter channels near the edge of the Brazilian wetlands.
At that hour, the river was usually calm enough to hear fish breaking the surface, birds shifting in the brush, and the soft slap of water against the side of the boat. But that morning, something else cut through the silence. Not a splash. Not the rustle of birds.Something deeper.
It came low and drawn-out, like a slow groan rising from beneath the water — but there was something off about it. Too steady. Too heavy. Not quite the sound of any creature Joaquim had heard before. He froze and slowly lifted his paddle out of the water, listening harder.
Then it came again.Only this time, it was closer.
