Part 1
The tide went out further than Kae had ever seen it, and did not come back on time.
She stood at the lip of the old seawall with her boots in her hand and watched the harbour of Mara empty itself — not the slow daily breath of the water, but a long withdrawal, as if the sea had remembered an appointment elsewhere. Boats leaned in the mud. The fishing skiffs that should have been afloat by now sat canted on their keels, and beyond them the exposed flats glistened a colour she had no name for, slate going to bone where the light caught it.
Low water, the old men would say, and spit, and mean nothing by it. But Kae had been drawing this coast since she was nine years old, and she knew the shape of low water the way she knew her own hand. This was not that. This was the sea pulling back to show her something.
She did not yet know it was a debt. She thought, looking at the bared mud and the boats lying down like tired animals, only that she would have to redraw the harbour line again, and that nobody would pay her for it. Maps of a shrinking world sold poorly. People did not like to be reminded that the edges were moving in.
Behind her, up the terraced slope of dying vines, the bell of the council house rang once — flat, cracked, the way it had rung since before she was born — and then was silent. She turned toward it because there was nothing seaward worth turning toward, and because the bell, like the tide, was early.
Part 2
Her grandmother’s debt was written in a hand Kae could not read, in a ledger she had not known existed, on a page the council clerk turned toward her with two fingers as though it might be wet.
“Hurshi script,” he said, not unkindly. “Old form. Your grandmother signed it. The mark is hers — you can see the cartographer’s notch, there, she put it on everything.” He tapped the margin where a small careful cut interrupted the ink. Kae knew the notch. She made the same one. It was the closest thing her family had to a name that travelled.
“Signed it for what?”
The clerk spread his hands. “Passage. Materials. The library on Hursh lent against the survey she never finished. The interest has done what interest does.” He said it the way people in Mara said everything now — as if the world were a tide that only went out. “It falls to the blood. That is also old form.”
Kae looked at the number at the foot of the page. It meant nothing to her as a quantity; she had never held that much, never seen it, could not have spent it if it had rained down on the harbour. What she understood instead was the shape of the thing: a coastline her grandmother had been paid to map and had not delivered, a coastline that — Kae was almost certain — no longer existed to be mapped.
You cannot survey what the sea has taken, she wanted to say. But she had spent her whole life proving that you could draw a thing after it was gone, that a line on vellum outlived the rock it described. That was the trade. That was, she was beginning to see, exactly the trap.
Part 3
Passage to Hursh could be bought in only one currency Mara still produced: a thing the buyer wanted more than money. Kae had two such things. One was her hands. The other she did not like to think about.
The Hurshi factor kept his office above the chandlery, in a room that smelled of tar and the inside of other people’s purses. He was younger than she expected and wore the high sand-coloured collar of the Bureau, the bronze clasps catching the lamplight as he breathed. He listened to her debt with the patience of a man who already owned the ending.
“The library will discharge it,” he said, “for the survey. The original survey. Completed.” He let that sit. “We will carry you across. We carry everyone across, eventually.” A thin smile. “It is the coming back that people find expensive.”
“I draw what’s there,” Kae said. “The coast she was paid for isn’t there anymore.”
“Then draw what isn’t.” He turned a signet ring on his finger, once, a small private motion. “You would be surprised, cartographer, how much of Hursh is built on maps of places that have gone under. We do not keep them because they are accurate. We keep them because someone, somewhere, still wishes to go.”
She signed with the notch, because there was nothing else to sign with, and because somewhere still wishes to go had lodged in her like a hook. Outside, the tide had finally turned and was coming back in over the flats, unhurried, indifferent, covering everything it had shown her that morning as though it had shown her nothing at all.
