The Cartographer and the Blade

Orla Tallis is the youngest master surveyor the Ostmere guild has admitted in thirty years, and she has built her name on not repeating her mistakes. She carries the two she has made rolled in the bottom of her dead father’s instrument case: a ford drawn eleven miles out of place, a ridge two hundred feet too high. Now the Crown has sent her into the Ashfall, the upland two crowns have argued over for sixty years, to survey it true before the treaty talks at Stannock. Six months on foot, the Brack valley last, for reasons of season. And an escort she did not ask for.

Corin Stroud is a former garrison captain, cheap and quiet, his name written into the Chancellery’s warrant in a different ink. He has repacked her mule before she reaches the gate. He picks every route and gives her the reasons after. He never says safe; he says fine, which is worse. And on the first morning he tells her he has used her first map. He was on it.

Across a ferry whose ferryman knows a soldier by how he stands a mule, up a rotten watchtower in the wind, through three days of rain in an empty steading, Orla learns to read a track and Corin learns to read a contour, and they begin to walk in step. She has never asked for anything she could not first measure. He has arranged his whole life so that nothing he cares for is near enough to be hurt. And the Chancellery asked for him by name, and he has not said why. The Brack is at the end of the road, and whatever she draws there, both crowns will read.
