Excellent descriptions, and you're very careful to make an observation after your character knows a fact...for instance, your character doesn't 'know' someone's name until after she's heard it used by one of the pack members. That's a good writer's observation.
But, I'd like to know more about your runaway, Taylor. Maybe you could add to your prologue and tell us why she's running away. What about her home life is so bad? Abusive or neglecting parents? Folks too strict? Rotten kids at school? Boyfriend issues or trouble with the law, maybe? The boys will want to know when they start talking to her.
These are just some helpful suggestions...use them or toss them at will. Good luck with your story!
