In the thrilling conclusion to the Shadow of the Raven trilogy, the near-death Queen Lyrna is determined to repel the invading army of the Volar Empire and restore independence to the United Kingdom. But to achieve her goal, she will have to do more than just rally her loyal supporters. She must unite with forces that once seemed abhorrent to her—those who possess the strange and varied gifts of Darkness—and wage war against the enemy. Vaelin Al-Sorna will help her queen reclaim her possessions, but the path is difficult, for The Volar enemy has a new weapon that Vaelin must destroy—a mysterious Ally capable of granting unnaturally long lives to his servants. And defeating someone who cannot be killed is a nearly impossible feat, especially since Vaelin's bloodsong, the mystical power that made him a legendary warrior, has fallen silent.
