A Dream of Snow — Yasmine Galenorn

Asajia and Bran have managed to escape, but now they must plan how to overthrow Bran's brother, Karehl, who is set on destroying the legacy Bran's father left for them. With the Lorani behind them, they must flee to Swelan, where the People of the Winds live. Once there, brother will go against brother, and Asajia must prepare to become queen of the Wolf People...if Karehl doesn't assassinate them first.
