"Keep the ribbon," she told me, and this time her voice cracked like thin ice. She put it into my palm and closed my fingers over it. The ribbon was warm and smelled of thyme and soot.

I'll assume you want a short creative piece titled "I Raft You, Big Sister Is a Witch" and write a new, polished vignette. If you meant something else, say so and I'll adjust.

At night, in the house she had left like a bookmark between chapters, I sometimes dream she walks back across the threshhold with pockets full of storms and cherries and stories stitched into the hems of her dresses. But dawn always finds me holding the ribbon, fingers pressed to the pulse at my thumb, and I know the truth most small and bright: some people are made to move like water, rearranging the shorelines of other lives so that those lives can find their own channels.

When the sun dipped toward the shoulder of the hills she stood and spread her arms, and the sky listened. Her shadow grew tall and not-quite-right; it licked at the treeline like a tongue. I watched as something like a compass of stars spun over her head and the ribbon at her wrist braided itself into a loop and unlooped, a slow breathing. The canoe felt smaller then, as if we were children again and the world had folded up around us.

We cut the current by the ruined mill and drifted beneath sycamores. She reached out and touched the bark, whispering a name I didn't know; the tree's leaves sighed and loosened a shower of tiny, paper moths that glowed briefly and then dissolved into river smoke. I should have been startled, but I only laughed until the sound made the water tremble.

When the world grows too certain, I untie the ribbon and let it dip into the river. It does not sink; it glows faintly, a light beneath the surface, as if to say the map is not gone—it is only being redrawn.

"Promise me," she said, "when I vanish, remember the river."

Her laugh rippled like thrown glass. "I never draw maps. I make signs."
