Critique:
I've never been a huge twi-hard, but I must say Alice is my favorite character:). I think you managed to capture her personality and character traits really well. It's a very good plot too, I love the whole idea of Twilight from Alice's point of view!
However, I did notice that he dialogue seemed like it needed just a little bit of tweaking. Nothing big, I just thought I'd point that out.
Again, great story, keep writing!!!!
