Not only will this ensure her safety but it will forge an alliance that is sorely needed.

When the first she-wolf in over a millennia is brought before the Queen, a fierce curiosity leads to a hasty claim. Has she made the right choice? Can this she-wolf protect her when strange desires and ancient threats begin to surface?
