I absolutely love Twilight and have been thinking about this idea for a while. Please let me know what you think and if I should continue

Basically my story will be about a young Cullen named Islaina, she is 17 years old and currently attends a Boarding School in England. In this story Bella and Edward aren't married yet, but Jacob and Bella are still close friends.

Here is what I have for my story so far, please review! I know it's not very long but its just a starting chapter. I will continue if you like it!

Bella was curious to know what had got all the Cullen's in such a frantic state. She turned to Edward hoping for an answer "My sister is coming to stay" Edward answered Bella's question before she had even asked it. Although Edward couldn't read Bella's mind he had got quite good at guessing what she was thinking.

"You have another sister?" Bella questioned, Edward had never mention her before.

"Yes her name is Islaina, she is 17 and goes to school in England" Edward explained. Bella frowned "17? Not 117?"

Edward smiled "Yes 17, the same age as you"

Islaina had arranged to travel home at night so Carlisle and Esme could collect her from the airport. Alice had gone with them to fetch her; she had missed Islaina while she was away.

It wasn't long before Esme spotted the teenager in the crowd of arrivals. "She's there" Esme cried as she rushed towards her.

Islaina was a petite brunette; she had golden brown eyes and pale skin. She was wearing track pants and a pink vest top. Alice frowned as she looked at what the young girl was wearing "What happened to the dresses I sent you?" she asked.

"Track pants are more comfortable to travel in" Islaina smiled as she hugged Carlisle "Hey Daddy"

"Hey sweetie, how was you're flight?" Carlisle replied as he took her hand luggage. Alice put her arm around Islaina and led her out of the airport towards the car.

"I was ok I guess, long and boring but fine" Carlisle and Esme threw eachother a smile. She hadn't changed at all.

"So is she a…" Bella wondered, Edward hadn't told her much about Islaina

"No, well kind of Islaina is a little different to us, she is half human half vampire" Bella looked even more confused. Edward's explanation made no sense top her at all.

"How can she be half…is that even possible?" she asked him curiously.

"Yes, Islaina's mother was human. But her father was a vampire" Bella's eyes widened. Before Bella had chance to ask him any more questions she was interrupted "They're here" Edward smiled, he could read their minds as they drove towards the house.

Bella rushed out of Edward's bedroom and headed downstairs, as she got to the bottom Edward, Emmet and Rosalie were already stood at the door. Damn vampire speed Bella thought to herself. I will beat him one day.

As the door opened the Cullen siblings rushed toward the pretty petite brunette. "Ok, still part human" Islaina gasped as she was pulled into a group hug. Her siblings released her quickly, before taking a step back. Jasper had now come into the room "Jasper" Islaina smiled; she knew Jasper was still uncomfortable around her.

"And you must be Bella?" Islaina said as she walked slowly towards her. Bella nodded nervously "Alice told me all about you, I'm Islaina but I prefer to be called Izzy"

Islaina pulled Bella into an uncomfortable hug; Bella was a little shocked that Islaina felt warm. She smiled as she looked up into the eyes of the newest Cullen member and moved away awkwardly.

"What's for dinner I'm starving?" Islaina grinned as she headed towards the kitchen.

"Yes she eats too" Edward smiled as he noticed Bella looking at him for answers again.

The Cullen's followed Islaina into the kitchen, although they were pleased to see her, Bella couldn't help but noticed the nervous tension that now filled the house. Something was worrying the Cullen's they seemed uneasy about Islaina's return.

Please review and let me know what you think, I have so many ideas for this fanfic!

Also just wanted to point out Islaina will develop a relationship with Jacob, and the identity her father is another twist in the story. Don't really want to give too much away though.
