My start.

Lira is no ordinary girl. Not when her other half is a wolf. she dosent know how or why.
Erin is just an ordianry boy. He has wactched the wolf pack since he was young.
Lira knows Erin. Erin dosent kbow Lira. He only knows Linger, the white wol of the pack, that strangly appers after Lira goes away.
But balance is disrupted. Its winter... an Lira is changing bavk. she has to find out which world she must stay with....
