She was his weakness. They never knew she was his secret. ————————————————— For four years, Elowen Vayne carried the weight of a marriage that was killing her. They called her sickly. They called her a poor excuse for a Luna. They never asked why a healthy young noblewoman wasted away in her own house — and she never told them, because she didn't know.
