"There are many rooms in the Winter Court, but none shall take you out of it."

The Cait Sidhe has been defeated. James, Cai, and Cecil's sister, Vera, are alone on the wild moors. But there is no time to rest or mourn. Deirdre and Iain are trapped in the Winter Court after the young faery was lured there by the Winter King. He assigns an unwilling Raisa, the Winter Queen, to train Deirdre to control her wild, unstable magic, a task that is fraught with peril for both women. Iain is isolated, encased by protective magic – but it may not be enough to keep him safe from all the dangers and schemes of the Unseelies.

As the Unseelies embark on their Wild Hunt and pave the way for an invasion, the Iron Guard moves to recall their people from the area of the Summer Court, led by Edgar Windsor, the heir to the throne and Alvey's uncle. He and his men are on a collision course with both the Seelies and their captive, General Alan Callaghan, who is guilty of high treason. With his fate uncertain, Alan dreams of reconciliation and forgiveness from his family. But he must first grapple with his crimes against the Seelie faeries and the human army.

The Stolen Vow is book six in the seven-book Winter's Blight series.
