What Am I?? Twillight story

"Hi Andrea,
I'm on a bus to Volterra right now, we have about four hours left. God, it's hot in here, it's like they have never heard of air conditioner! Sonia is sleeping on the seat by mine, drooling...I'll take some pictures of that, don't worry.
Thank you for your present, I LOVED it! I'm wearing the necklace all the time...I am very sorry that we didn't celebrated my birthday together, but we'll do it next year! I still can't believe I'm seventeen now! It's so old, isn't it? Hah, only joking - i LOVE it! Sonia and I celebrated my birthday in a club in France, it was soo amazing! I'll tell you all about it when I get back...
I'm okay, tough I was feeling little funny past few days... my head was spinning couple of times and i had a couple headaches...it must be because that dog bite a got couple of weeks ago...it was just a puppy, like a little black German Shepard dog... Sonia thought it had rabies, but doctor said it was all okay...
How are you guys? What's up with you and Marc? Did you kiss or what??? Hug all of them for me,will you? I'm coming back soon, I'll call you when I get back...
Write me back, love you
Joan....

"Follow me, please" said our tour guide. I was on a trip trough Europe with my friend, Sonia, and we were now in Volterra for the St. Marcus Day festival or something like that. Our tour guide, Heidi, was taking us to see a castle in the center of the city. She was strangely beautiful, with her pale skin and a perfect face. Every male in our group was drooling, and every female was pissed about it, making Sonia and I crack of laughter.This trip with Sonia was so amazing, too bad it will soon end. But I was feeling happy, because I knew I will soon be back to my hometown and my normal life... I was so wrong.
After a fifteen-minute tour trough the halls, she led us to a big hall. An amazingly cute guy passed us, followed by a couple and an exotic looking girl. He said something to our tour girl and smiled,but I was too far from them to hear. Our eyes locked for a second, but he quickly looked away. Sonia saw that and she started giggling. I was still thinking about him when I entered the hall. A big group of beautiful people in robes welcomed us with huge smiles.
I was far from prepared for what happened in next few seconds...
