Kira and the Magic Stone

n a world where maps hold magic — where the borders drawn by a skilled hand can reshape rivers, summon mountains, and seal away ancient evils — the art of cartography has been outlawed for a century.

When seventeen-year-old Sable discovers a hidden atlas beneath her late father's floorboards, she unknowingly breaks the seal on a darkness that was never meant to be found. Now hunted by the empire's Map Wardens and guided only by a compass that points not north, but toward what she fears most, Sable must journey across unmapped lands to reach the edge of the known world — before the blank spaces on the map consume everything within them.

But the closer she gets to the truth, the more she realizes her father didn't stumble upon the atlas by accident. He drew it.

Want me to refine this — change the protagonist, the magic system, the setting, or the stakes? I can also write multiple versions if you'd like options.
