Beneath Ceaseless Skies - Do Not Look Back, My Lion by Alix E. Harrow

Eefa looks back. Talaan is bed-tousled and half-dressed astride a yellow mare, her hair a tangled mane behind her (how many times has Eefa combed that hair, gently, in the glow of the fire?), her robe fallen open to the chest (the laundry Eefa washed the previous day, folded with lavender and cloves). Her feet are bare. She does not seem to feel the white-toothed wind nipping at her flesh.
