Ripple taps his little tail along the warm current, counting the green kelp fronds as he glides. One. Two. Three. Four. The water smells of sun-warmed stone, and his fins swing loose and easy. He thought the day would last forever, right here, right now.
Then a dark swirl behind him yanked his fins wide and tumbled him sideways, far off the path. The kelp fronds blurred past in a green streak. Thump. The current grabbed hold and refused to let go. His mouth opened on a soundless 'oh.'
He pressed his belly flat against the cold, smooth underside of a passing boulder. Silt gritted between his scales, thick and grey, and the pale blue of the shallows shrank tiny behind him. Deeper. Thinner. Colder. He thought: I don't know which way is home.
The current pulled him forward into the dark, and the water stopped tasting of sun. Now it tasted of pressure. Of depth. Of a slow, deep hum that vibrated through every single scale. He thought the hum sounded like the whole ocean holding its breath.
Eight pink arms burst out of a coral arch and wrapped around him tight, tight, tight. All eight ink-dark eyes winked at once. 'LISTEN,' the octopus rumbled, and the whole channel shook with the sound. Her grip was warm and sticky and absolutely not letting go.
'The deep channel runs south. Follow the water that hums like a held breath, and you'll hear it shift from low to bright.' She let go with a wet thwip and sank back into her arch, already humming to herself. Ripple dangled in the current, fins still, listening for the shift.
A copper seahorse darts out of a hermit-crab shell and clamps his tail around Ripple's side-fin, yanking him sharply east. 'Wrong way, my mistake,' the seahorse mumbles, flushing rust. He releases Ripple and melts back into his shell, and the water suddenly smells faintly of sunshine.
'When the water stops tasting of salt and starts tasting of sun-warm, the reef is right under you.' The seahorse's words hung in the cold, then a faint golden scent threaded through. Ripple's fins twitched. He thought: sun-warm. Like the top of the shallows. Like home.
The current doubled and the blue went black. Ripple's fins pinned flat, straining, while the hum dropped into a deep, grinding roar. The seahorse's tail locked tight, the octopus's arms wound from behind, pulling, holding, holding. Then all three swung sideways in the dark, the roar swallowing every sound.
Then the roar cracked open like a shell, and golden light poured in. The reef was there — every brain and fan and tube exactly where he'd left them. The water tasted of sun and salt and the little chalky smell of home. They drifted in the warm current, three of them, as the hum steadied. Bright. Steady. Home.
