Penelope is not a normal girl. Her parents left her in the forest when she was only a baby. A pack of wolves found her at the point of near starvation. They took her in and raised her as her own. She followed their custom, ate what they ate, and did what they did. They taught her how to hunt, sniff out danger, and more. Twelve years later she was found and brought into society for her own protection. The language of the new people is quite different than what she was used to.

Can she finally get used to the human life, or will she cave and go back to join the only family she truly knows
