   Summary

   ​Kiera expected a rival who would tear her marriage apart with a cruel smile. Instead, Aerion Targaryen returned from Summerhall with cold eyes, perfect manners, and a terrifyingly quiet mind.
   ​He doesn't look like a boy playing for a crown—he looks like a man who has already lived a lifetime, seen how the world ends, and just wants to be left alone.
