Track of the White Wolf - Chronicles of the Cheysuli, Book 4

Niall, Prince of Homana, key player in a prophecy that spans generations, should have been the treasured link between Cheysuli and Homanan. Yet neither of the peoples he is destined to someday rule feel anything but suspicion of Niall. Homanans fear him for his Cheysuli heritage, while Cheysuli refuse to accept him as their own because he has acquired neither a lir-shape nor the lir companion which is the true mark of the Cheysuli shapechangers.
And now, despite his precarious situation within the kingdom, Niall must undertake a journey to fulfill yet another link in the ancient prophecy. He must travel through war-torn lands to claim his bride—a mission which may prove his doom. For searching for both his destiny and his lir, Naill is about to be plunged into a dangerous maelstrom of intrigue, betrayal, and deadly Ihlini sorcery.
