Shadow Leader: Tales of the Wolves, Book 2

Dion; her wolf, Gray Hishn; and their friends have just escaped from slavers and are trying to return home so that they can warn their people about the likelihood of impending war. Dion and her wolf share a telepathic bond. Together they are superior scouts of terrain, and her wolf amplifies Dion's healing abilities so that together they can heal people wholly. Nonetheless, they face many battles as they make their way.
There is much gritty fighting that needs doing, many frozen mountains that need to be traversed, and enemy agents scour the countryside for the group that includes them. Now Dion's abilities may make her stand out and bring harm to her friends.
