The Shadow of Time's Courage — Meyari McFarland

The mud-walled hut was something she'd expect from the poorest of Mama Rosario's people, not someone who worked at court. Except no, it wasn't Su Magee. Ancient magic was warping the world around Su Magee's house and Xun was the only one who could fix this. If she had the time before the effect was lethal.
