   Summary

   It is the law that a monster cannot take a lover who is not their Soulmate. Doing so is an unspeakable crime against the will of the Fates. Those who commit this crime are marked Unfaithful—the greatest shame a monster can endure.

    

   Truth be told, Rus had never been a monster of great faith.
