In a necropolis in the wilds of Canada, he seeks refuge and finds the last great creatures of the world - the shape-shifters known as the Nightbreed. They are possessed of unearthly powers-and so is Boone. In the hunt for Boone, they too will be hunted. Now only the courage of this strange human can save them from extinction. And only the undying passion of a woman can save Boone from his own corrupting hell...
