BOOK THREE to The Crystal Series. Nik and her friends find war on every front in their lives with the guidance or Atiweh and Tarrent. As the Valkyries' power grow and relationships are built and broken, the people in Elantris hear word of an attack on Aegran. The heirs of each kingdom must unite stronger than before to bring the peoples of Tarsen together against Erix's force of new creatures. Creature that has not been seen since the war between the Seelie and Unseelie Courts. Erix grows all the stronger in Salvare and closer to his end goal with the help of his Wild Hunt. Gyda leads her company and follows orders, but to what end? Gyda learns that Tarsen is not the same world she left behind following the war. Seeing Tarsen angers her and awakens something inside that she never had planned.
