The hum of the engine and the rhythmic creak of the ship replaced the melody in Iris Carter’s mind, though she wasn’t sure which she preferred. She leaned over the railing of the Horizon, her research vessel, and stared at the dark expanse of water below. Moonlight danced across the waves, but its beauty felt distant, unreachable.
“You should get some sleep,” Alex Rivera’s voice called from behind her. Isla turned to see her research partner and best friend standing with a thermos of coffee in hand.
“I will,” she lied, rubbing at her tired eyes.
“You said that last night,” Alex replied, joining her at the railing. He took a sip from the thermos, his expression softening. “Look, I know this coral project means a lot to you. It means a lot to me too. But you’re no good to it if you collapse from exhaustion.”
Iris sighed. “I just can’t shake the feeling that we’re on the edge of something big. The glowing coral, the patterns in its decay it’s unlike anything I’ve seen before.”
Alex raised an eyebrow. “Or it’s just another ecological disaster caused by humanity’s greatest hits: pollution, overfishing, and climate change.”
“Maybe,” Iris admitted, though her instincts told her there was something more. Something deeper.
Before Alex could press further, Captain Marjorie Blake’s voice crackled over the ship’s intercom. “Crew, report to the lab. We’ve got a new batch of footage from the dive camera.”
The lab was small and cramped, its walls lined with screens, instruments, and hastily scrawled notes. Iris and Alex stood shoulder to shoulder, watching as the footage played on a monitor. The underwater camera had captured stunning images of glowing coral, its faint light pulsating like a heartbeat.
“Look at the spread,” Alex said, pointing to the screen. “The glow is intensifying along the reef.”
But Iris's attention wasn’t on the coral anymore. A shadow flickered at the edge of the footage just a blur at first, but unmistakably humanoid. She froze, her heart skipping a beat.
“Did you see that?” she asked, her voice barely above a whisper.
Alex frowned. “See what?”
“Rewind it,” she said, leaning closer to the screen.
The footage replayed, and there it was again. A figure, sleek and fast, darting through the water just beyond the coral.
“It’s probably a fish,” Alex said, though he didn’t sound convinced.
“Fish don’t move like that,” Iris replied, her voice edged with something between curiosity and dread.
Marge appeared behind them, her arms crossed. “It’s just a trick of the light,” she said, her tone firm. “The ocean’s full of strange things. Don’t let your imagination get the better of you.”
Iris glanced at her, noticing the tightness in Marge’s jaw. The captain knew more than she was letting on, but Iris decided not to push yet.
That night, Iris sat on the deck alone, the chill of the ocean air seeping into her bones. The footage replayed in her mind, along with her mother’s warning. She stared out at the waves, trying to quiet the unease building in her chest.
And then she heard it.
The melody drifted through the air, faint but unmistakable. The same song her mother used to hum. It wasn’t possible it couldn’t be but there it was, weaving through the sound of the waves like a ghost.
Iris’s breath hitched. She turned, searching for the source, but the deck was empty. The song seemed to rise from the ocean itself, filling her ears, her mind, her chest.
The sea takes more than it gives.
Her mother’s voice echoed in her memory as she gripped the railing, the melody growing louder, clearer. And for the first time in years, Iris felt like a child again small, uncertain, and afraid.
