From publisher blurb:
Even a man who is pure of heart may become a wolf when the wolfbane blooms and the autumn moon is bright!
Mankind has come far since his ascendancy from apes, but behind the facade of reasoning and civilization he projects he is still an animal.
Deep inside every man lurks a ferocious beast, a terrible creature that can develop a life of its own. This book details those beasts.
The contents of this book include the history of these ferocious beasts, means by which a man might become a shapeshifter, supernatural powers that transform these creatures into truly terrifying foes, statistics for a variety of stock shapeshifters, and a number of unique villains.
