Okay, I don't actually remember this book a whole lot, but I'll try telling you guys what I do remember:
First thing that I should say, I don't think it was an actual werewolf book, but it had wolves in it. So, getting to the point.... There was this girl who lived with wolves I think for most of her life, but then had to go live with her aunt or grandma (one of the two)--or vice versa (she lived with her aunt or grandma and then ended up living with wolves).  And.... crap, there was something else..... okay, I can't remember what else I was gonna say, but this is just about what I remember.  The title I think might have been Fangs, but I looked for any book that matched my description with the title Fangs, and I couldn't find any thing.  Sorry that this is pretty vague information, but I hope that at least one of you guys know what I'm talking about.
Thanks!
