A/N: Thank you so much for clicking on this story. I do apologize if the summary wasn't that good and I hope that you find the story interesting. I always wondered how Bella would do with a sister, whether she is younger or older. I've seen the stories of her having a sibling who ended up with Jacob Black or Paul. No hating on those stories but I wanted to try something a little different. So please enjoy and let me know what you think whether it's in the reviews or in a private message.

Disclaimer: I do not own Twilight. If I did, Jacob Black would not have imprinted on Renesmee. Sorry, not sorry.

People always told me that I was my mom, in looks and personality. Somehow, I didn't know how that set with me. Don't get me wrong, I loved my mom. I visited her every summer and spent a few weeks with her. I loved the sun and the adventure we would usually end up on but I was always glad when I got back in Forks with my dad.

My parents had divorced when I was two years old, after the birth of my younger sister, Bella. Mom couldn't take the rainy weather that stuck around Forks and was desperate to get out. However, dad wouldn't let take both me and Bella. So, they made the agreement that he would keep me, since I was unbearable to be around when I wanted dad, and she took Bella. Sixteen years later, I was completely fine with that agreement.

Life had gone just fine for me and dad. Sue Clearwater, who was married to one of his best friends, helped him raise me and in result, I grew close to her daughter, Leah. While we went to separate schools, I considered her to be one of my closest friends. If there was ever any "girl issues", I was automatically sent to Sue for help. So, the Clearwaters quickly became my second family.

So, when Leah's boyfriend of two years disappeared, I was right there with her, comforting her. Sam Uley was usually the responsible type, so this shocked everyone. Allison, his mom, said that he had gotten a letter from his father and walked out.

Two weeks later, he showed back up, without a word of what had happened and where he had been. Leah said he had confided in her dad and Quil Ateara III, but refused to say anything to her. That was about a month ago. He was lucky that I didn't tear into him yet. This was mainly for the reason that I hadn't seen him since before he disappeared.

My name was Katherine Swan, but everyone called me Kat or Katie. I had just graduated from high school and had plans to attend college in Port Angeles for elementary education. I had gained my mother's light brown hair but my dad's dark brown eyes. With the visits I made to Arizona and the two week trip me and dad made to California with Bella, I got nicely tanned in the summer.

"I'm so worried Kat." She brushed her gorgeous black locks out of her face before trying to apply her make-up for school. Today was the last day for La Push. Forks High School got out a week earlier than La Push did, so I was enjoying the break while she was forced to go to school. She would get the laugh when I started a week before she did.

Leah was beautiful in an exotic way. She had perfect copper skin and eyelashes like feather dusters, and stood around 5'10" tall, putting my 5'5" height to shame. One of my favorite things about Leah was her ability to tell how things were without sugar coating. She was extremely loyal and protective over her loved ones.

"What if he's cheating on me?" She bit her lip.

"Honey, he'd be blind if he ever tried to cheat on you. You're completely gorgeous." That seemed to satisfy her. Another thing about Leah was that she knew that she was pretty. While she liked confirmation, she wasn't one of those girls who needed to be constantly told.

"I feel like he's barely putting anything into the relationship anymore." She confessed. "Remember that house that he's bought when he graduated early in December?" Once I had nodded, she continued. "I asked him if he still wanted me to start moving in this summer and he just shrugged. It's like he doesn't care." Yeah… I had to have a talk with this Mr. Uley.

"Leah, you're going to be late for school." Sue poked her head into Leah's bedroom. "You know that you and Kate will be hanging out once you get out." She smiled at me before leaving. I assumed that she was trying to shuffle Seth, Leah's younger brother, along.

"I just want things back to how they were before he left." She sighed unhappily. After glancing at the clock, we realized that if she didn't leave now, she'd be late. Since her car was being worked on, I offered to drop her off so Sue would only have to take Seth.

"Do you need me to pick you up?" I asked her as I pulled into the La Push High School parking lot. Most of the small parking lot was filled with older, worn down cars. Mine was no exception.

She shook her head. "Emily is coming down from the Makah reservation. She offered to pick me up." Emily was Leah's cousin and also one of my friends. She came down for a week or two every summer and Leah would go up there for the same amount of time.

After pulling out of the parking lot, I decided that I had one destination before I made it back to Forks. Regardless of what he went through in those two weeks, he has no right to treat Leah like this.

Sam's house was a good five minutes away from the high school. It was near the woods, which made Leah nervous, especially after his two week disappearance. It was a tiny house that looked gray. There was only one narrow window beside the weathered blue door. A dirt path led up to the porch which looked a little unsafe. Nevertheless, I parked my car and made my way up to the door.

After a few seconds of constantly knocking, no one had come to the door. Sam hadn't gotten a job from the best of my knowledge except for doing odd jobs for the reservation. His old truck sat in the make-shift drive-way. I knew I was in the right place since me and Leah had stolen the truck before to clean it up.

"Samuel Uley." I demanded. "Open this damn door. Stop being a coward!" I banged on the door, opening to elicit a response from him. It took another couple of minutes before I got the desired effect. The door opened so fast that if I would have blinked, I would have missed it.

The first thing that caught my attention was his tan bare chest. While Leah had bragged about Sam's body, I had never paid that much attention to it. Now, I could see that she was right. Realizing that I was checking out my best friend's boyfriend's body after beating on his door and yelling at him, I felt a blush start to cover my cheeks. I started looking up till I was looking at his face. He looked as if he hadn't slept in a few weeks. His short hair was disheveled.

Then, I looked into his eyes. I was always convinced that my dream guy would have blue or green eyes since I had brown, but Sam's dark brown eyes were so mesmerizing that I couldn't remember why I decided not to date guys with brown eyes. His jaw went slack and he stared at me without shame much like I had stared at his abs. I shook my head. I did not come here to stare at him or to be stared at.

"Look. You're being a shitty boyfriend to Leah. I don't know what the hell is going on or what happened during those two weeks you were away but none of it is Leah's fault. So man up, apologize, and treat her like she deserves to be treated. If I find out that you've been cheating on her or continue treating her like this, I will kick your ass." He looked like I rendered him speechless.

"Have a nice day Mr. Uley." I gave him a polite smile before walking back to my car, getting in it, and driving away.
