Chapter 1.

Bella POV

"Bellllllllaaaaaaa! Please!" Alice whined as she bounced up and down. Edward and I were lying on the sofa in the Cullen's living room. We were watching Titanic, but the annoying Pixie decided that she was bored, and of course, I am the first person she truns to!

"No Alice!" I said pausing the film and sitting up. "I am not going shopping with you! I am perfectly happy here with Edward. Why don't you take Rosalie." I said, knowing that Rosalie will only hate me more after this.

"But Bella! I want to play Bella Barbie! And we could go shopping for Wedding stuff! How fun will that be?" She said, still bouncing.

Thankfully, my phone stopped her from saying anything else. I looked at the caller ID and nearly had a heart attack when I saw the name. "I have to take this." I said quickly before running outside and far enough away from the house that I wouldn't be overheard. I quickly checked to make sure I wasn't followed before answering. "Harry! What's going on?" I said quickly into the phone.

"Bella. I should have told you at the end of the year when it happened. I'm so sorry. It's Dumbledore." Harry said. I could hear the sorrow in his voice.

"What? What happened Harry!" I nearly yelled, only just remembering to keep my voice down.

"He's... Bella... He's dead. Dumbledore's dead." I felt my heart break in two. I fell to my knees on the floor. "He was murdered. Snape murdered him!"

"SNAPE!" I screamed, not caring if the Cullen's heard. I didn't care about anything anymore. "Are you kidding me? That bastard! I'm gonna kill him!" I yelled, standing up and pacing. I was close to apperating to Hogwarts so I could kill Snape with my bare hands!

"Bella! Calm down!" Harry instructed, stopping my plans of killing Snape.

"Calm down! You expect me to calm down! Harry, this happened 2 months ago! And you're only telling me about it now! You should have told me when it happened!" I yelled at him. I saw the Cullen's stood at the window watching me, so I lowered my voice. " I'm coming home." I said.

"No! Bella, you can't! We're not 17 until tomorrow and you still have the trace on you! I called because you deserve to know! You have to stay there! You're safe there and I can't protect you if you're here." I decided not to correct him on the trace information.

"Harry! You're my twin! I know what you're up to! You're going to go hunting for Horcrox's! I'm not going to let you do that alone! We're a team! This started with the 2 of us and that's how it will end! You're not in this alone!"

"The answers still no Bella. My job is to protect you. Not to let you walk straight into danger!" Harry yelled back. We could both be extremely stubborn when we wanted to be.

"It's me he wants Harry! Not you! Me! I'm the reason Mum and Dad went into hiding in the first place! I'm the reason that you're now a target for living that night!" I screamed at him.

I heard him sigh and knew he wasn't going to give up. And neither was I. "I'm done arguing Harry. You do what you have to, and I'll do what I have to." I heard him yell my name before I hung up and threw the phone into the stream. I walked back into the house and picked up my bag, noticing the looks the Cullen's were giving me.

"I have to go." I said, walking towards the door, only to find that all of the Cullen's were stood infront of it.

"Not without telling us what is going on." Rosalie said. I looked at all of their faces and saw the same thing. Determination and hurt. I knew they weren't going to move, so I went to plan B.

"I can't. Not yet. I have to go. I have to finish something that I started years ago. I have to save my family." I said. I looked across all their faces. "I love you all. Remember that. I'm sorry." I said before apperating to Charlie's house so that I could grab my stuff.

There are some things I should mention. My real name is Isabella Lillian Potter. I am the twin of Harry Potter and I am the reason my parents went into hiding. You see, there was a prophacy made that 2 children, twins, would defeat Voldemort. The prophacy stated that only 2 of the 3 can live and when he found out one of them was a girl, he decided that he would kill the boy and when the girl grows up, he would make her his wife. Only, when my parents found out about this plan, they went into hiding. And when he found us, he killed our parents and realising that he couldn't leave either of us alive, he tried to kill us, but it didn't work and he ended up killing himself. Harry and I grew up with the Dursley's until we found out we were a witch and wizard and left to go to Hogwarts where we met Hermione and Ron and found out that Voldemort was still sort of alive.

When he came back to life in our 4th year, he declared that he would kill everyone I love until I agreed to be his wife. Dumbledore, Harry and Sirius decided it would be best for me to go into hiding, so, Dumbledore helped me fake my death and I was sent to live with Charlie Swan, a friend of my father's, and that is where I met Edward. Harry has kept me updated on everything that is happening in the wizarding world (except Dumbledore's death!). When he told me of Sirius' death, I was heartbroken! He was like the father I never got to know!

I packed my bag in record time, grabbed my wand and quickly worte a letter to Charlie, telling him where I was, and grabbed 2 letters I worte after Edward proposed to me, one addressed to the Cullen's and one to Edward, appologising and telling them I love them. I should also explain that I no longer have the trace on me as when I moved to America, the British ministry thought that the American ministry were going to keep an eye on me, but the American ministry don't even know I'm here! So I can use magic whenever I want!

I placed the letters for the Cullens on my bed and placed Charlie's on the kitchen table before apperating to the Dursley's house where I knew Harry would be. He is in for a whole load of shit when I saw him.
