Valdemar is once again in peril, threatened by Ancar of Hardorn, who has long sought to seize control of the kingdom by any means at his command.

Yet this time Ancar may well achieve his goal, for by harnessing the power of Mornelithe Falconsbane, the Dark Adept, he has set into motion a magical strike against Valdemar the like of which hasn’t been attempted in more than five hundred years—not since Vanyel, the last Herald-Mage, shielded the kingdom from attack by the deadliest of sorceries.

And with Valdemar’s ancient spell-generated protections finally breaking down, Queen Selenay, Herald-Princess Elspeth, and their people could soon be left defenseless against an enemy armed with spells no one in Valdemar has the knowledge to withstand.

But as the long dormant magic of Valdemar begins to awaken, Elspeth finds that she too has a mysterious ally—a powerful spirit from the long-forgotten past…

In The Mage Winds trilogy, which began with the best-selling novel, Winds of Fate , author Mercedes Lackey continues the epic that started with her first published book, Arrows of the Queen introduced readers to the remarkable land of Valdemar, the kingdom protected by its Heralds--men and women gifted with extraordinary mind powers--aided and served by their mysterious Companions--horselike beings who know the many secrets of Valdemar's magical heritage. None but the Companions remember the long-ago age when high magic was lost to Valdemar as the last Herald-Mage gave his life to protect his kingdom from destruction by dark sorceries. But now the protective barrier set so long ago over Valdemar is crumbling, and with the realm imperiled by the dark magic of Ancar of Hardorn, Princess Elspeth, Herald and heir to the throne, has gone on a desperate quest in search of a mentor who can teach her to wield her fledgling mage-powers and help her to defend her threatened kingdom.
