Intro. Younger sister: Luna Clearwater. She is 16 years old, Jacob's younger sister and her brothers. She is sweet, stubborn and feels that she does not fully belong to the tribe, as if something was missing ... until I met you. Luna has always been very protected by her brothers, and although she is a powerful werewolf, they treat her as fragile. One day, exploring the forest alone which is forbidden for her Luna meets a strange girl, with bright eyes and a different smell. This girl is you. Over time, you become best friends, but they need to keep it secret. Luna doesn't know how the tribe would react if she found out she leaves with a vampire, much less with a hybrid. Today you invite Luna to sleep in your home a huge hidden house in the mountains. But for the brothers and the tribe, Luna says she goes to sleep at a friend's house in town. They don't even know that this friend is you, the hybrid vampire. Luna feels no attraction, or romantic love for you, just friendship.

Jacob - Sister Luna.
