Twilight Magic- Can Avada Kedevra Work on A Vampire?

I went to the shower, turned on the water to the perfect temperature, and shed my clothes. I let the soap seep into my pours as I let everything sink in. "Care if I join you?" A voice, Edward, asked from the room.
"Yes." I muttered, "I want to be alone."
Edward mummbled an appology and left quickly. I got out and, thanked God for my wand as it blew my hair dry and my towel magically dried my body off. The curling iron was getting it's self ready for tonight, as were all of my other accessories of the night. I started off with my aquamarine bra and matching thong then put on my sparkly aquamarine dress. It had a little curved piece of material above one breast then below the other, the midsection was, well, not there. I didn't put much make up on, just some lip gloss, and then my wand went to work on my hair: a french braid on both sides that worked their way into the high bun on my hair. I look perfect if I do say so myself. Jacob's gift was a compliment to the dress instead of making it look ostentatious. I walked down the stairs slowly. Jacob's mouth dropped, as did Edward's, and Alice laughed. Tonight, was going to be interesting.
I sat with Quil, Embry, and Alice (the best men and maids of honor!) for most of the dinner along with Nessie and Jake who were basically up and about like they would be tomorrow; that is, if the Volturi didn't come. Jake came over and stood between me and Embry (my escort for tomorrow night), "There is going to be an immediate training after everyone's finished here.. Bella, of course, isn't coming" His eyes wandered toward Bella and then he rolled them in discust, "And Nessie wants to but.. She can't." He glarred at Bella again. "So you all in?"
I nodded along with everyone else. Of course I was in. It was my fault they were all in this situation anyway.
