The Year's Best Science Fiction, Vol. 20

After another minute the water no longer seemed as cold. Through gaps in the cloud cover the sun was harsh on Naqi’s cheek. It etched furiously bright lines in the bottle-green surface of the lagoon, lines that coiled and shifted into fleeting calligraphic shapes as if conveying secret messages. The calm water lapped gently against their upper bodies. The walls of the lagoon were metre-high masses of fuzzy vegetation, like the steep banks of a river. Now and then Naqi felt something brush gently against her feet, like a passing frond or strand of seaweed. The first few times she flinched at the contact, but after a while it became strangely soothing. Occasionally something stroked one or other hand, then moved playfully away. When she lifted her hands from the sea, mats of gossamer green draped from her fingers like the tattered remains of expensive gloves. The green material slithered free and slipped back into the sea. It tickled between her fingers.

“Nothing’s still happened,” Naqi said, more quietly this time.

“You’re wrong. The shoreline’s moved closer.”

Naqi looked at it. “It’s a trick of perspective.”

“I assure you it isn’t.”

Naqi looked back at the raft. They had drifted five or six metres from it. It might as well have been a kilometre for all the sense of security that the raft now offered. Mina was right: the lagoon was closing in on them, gently, slowly. If the lagoon had been twenty metres wide when they had entered it must now be a third smaller. There was still time to escape before the hazy green walls squeezed in on them, but only if they moved now, back to the raft, back into the safety of the gondola.

“Mina… I want to go. We’re not ready for this.”

“We don’t need to be ready. It’s going to happen.”

“We’re not trained!”

“Call it learning on the job, in that case.” Mina was still trying to sound outrageously calm, but it wasn’t working. Naqi heard the flaw in her voice. She was either terribly frightened or terribly excited.

“You’re more scared than I am,” she said.

“I am scared,” said Mina. “Scared we’ll screw this up. Scared we’ll blow this opportunity. Understand? I’m that kind of scared.”

Either Naqi was treading water less calmly, or the water itself had become visibly more agitated in the last few moments. The green walls were perhaps ten metres apart, and now were not quite the sheer vertical structures they had appeared before. They had taken on form and design, growing and complexifying by the second. It was akin to watching a distant city emerge from fog, the revealing of bewildering, plunging layers of mesmeric detail, more than the eye or the mind could process.

“It doesn’t look as if they’re expecting a gift this time,” Mina said.

Veined tubes and pipes coiled and writhed around each other in constant sinuous motion, making Naqi think of some hugely magnified circuitry formed from plant parts. It was restless living circuitry that never quite settled into one configuration. Now and then chequer-board designs appeared, or intricately interlocking runes. Sharply geometric patterns flickered from point to point, echoed, amplified and subtly iterated at each move. Distinct three-dimensional shapes assumed brief solidity, carved from greenery as if by the deft hand of a topiarist. Naqi glimpsed unsettling anatomies; the warped memories of alien bodies that had once entered the ocean, a million or a billion years ago. Here a three-jointed limb, here the shieldlike curve of an exoskeletal plaque. The head of something that was almost equine melted into a goggling mass of faceted eyes. Fleetingly, a human form danced from the chaos. But only once. Alien swimmers outnumbered human swimmers vastly.

Here were the Pattern Jugglers, Naqi knew. The first explorers had mistaken these remembered forms for indications of actual sentience, thinking that the oceanic mass was a kind of community of intelligences. It was an easy mistake to have made, but it was some way from the truth. These animate shapes were enticements, like the gaudy covers of books. The minds themselves were captured only as frozen traces. The only living intelligence within the ocean lay in its own curatorial system.

To believe anything else was heresy.
