Legend of the Werewolf [EPUB ebook] 

Horror stalked the streets of Paris.As a child Etoile had run with the wolves and killed with the wolves. Then he was brought to civilization and his past was forgotten. But not when the moon shone full! Then he could not fight the bestial urges his body felt. The wolves called Etoile and the animal within responded, compelling him to stalk the streets of Paris, thirsting with vulpine ferocity for the taste of blood.
