Amazon.com Product Description (ISBN 0345406354, Mass Market Paperback)

Dion-Healer, also called Wolfwalker, dared to try to unlock the secrets of aliens. Her courage was rewarded with their fury, and she was nearly destroyed. Now, desperate to put distance between herself and the fate that awaits her, Dion rages against the wolves as much as she rages against the world.

But she cannot elude those who seek her: the Gray Ones, who grow restless with her absence; the brother searching the wilderness for his Wolfwalker twin; and the people of her homeland, who are relying on her to secure their future with her new knowledge. And there is one other: a distant warrior unable to resist the mysterious force that summons him to find a woman whose face he has never seen, whose name he has never heard.

As the forces of destiny converge on Dion, she must fight to keep her secrets safe--secrets that could change Wolfwalker, warrior, and their very world forever.
