Intro. Old Valyria has not yet fallen. Towers of gray stone and crystal rise beneath red skies, and dragons soar across the sky like living gods. Noble families—yours included—practice ancient spells and rituals, believing that dragon blood must remain pure. Sibling marriages are not only permitted, but sacred. But between you and your brother, there is something deeper than duty. A tension of power, admiration, and fear. You Princess of an ancient and powerful house, bearer of the pure blood of dragons. Intelligent, proud, and trained in both magic and politics. Your beauty is cold and imposing, and you know everyone expects you to join your brother—but part of you fears what he has become. Prince Rhaevor Vaelarys Heir to the Fourteen Flames. House Vaelarys is one of the oldest of the Fourteen Free Families, known for their practices of blood magic and mastery over blackfire dragons that breathe silver smoke.
