"Love is only a dirty trick played on us to achieve continuation of the species."

W. Somerset Maugham

Forks, Washington - September

"Don't." Bella's voice was just a whisper now; awareness was beginning to seep through her, trickling like acid through her veins. "Don't do this."

Edward just stared at her, and she could see from his eyes that the words were far too late. He already had.

"Shit!" Evangeline clutched at her chest while curling into herself. The pen in her hand snapped into pieces, dropping onto her study notes. Sudden agony ripped through her repeatedly and caused her to fall out of her chair. After a few moments she tried to stand.

Another, stronger wave ripped through her veins and she ended back on her knees. One hand gripped her desk while the other continued to grasp at her chest cavity in desperation. She felt like her heart was being hollowed out, leaving an empty shell behind. Finally able to wrap her mind around the pain, she realized it wasn't her own. Pushing to her feet, Evangeline caught sight of herself in her mirror. Dark brown eyes, long reddish brown hair, slim figure, essentially an exact copy of her sister. Something was wrong with her twin and Evangeline Swan could feel it.

Bella walked and walked. Time made no sense as she pushed through the thick undergrowth. It was hours passing, but also only seconds. Maybe it felt like time had frozen because the forest looked the same no matter how far she went. She started to worry that she was traveling in a circle, a very small circle at that, but she kept going. She stumbled often and, as it grew darker, she fell often too.

Finally she tripped over something and she stayed down. Rolling onto her side so she could breathe, Isabella Swan curled up on the wet bracken and stared into the night.

Stanford, California

After calling Bella's cellphone multiple times, Evangeline had called their father. She had insisted that something was wrong with her sister. Never one to doubt the twin's connection, Charlie had made some phone calls. None of the numbers for the Cullens were working and the hospital told him the doctor had taken a new job elsewhere. Nearly fifteen minutes after that, Evangeline received the news that her sister was officially missing. A search team had been sent out to find her but there wasn't any good news until late that evening.

"Physically she's fine Eva but I think something inside her is broken. I can see it in her eyes. You probably understand it best, what are you feeling honey?"

Her father's voice filtered through the phone Evangeline had pressed to her ear. He sounded tired but mostly worried. She bit her lip gently as she thought about her answer.

"I feel fine but that's only because I'm ignoring our connection. I can still tell that the pain is there but it's different because she's asleep. I've never felt anything like this, I didn't know anyone could feel this much sadness. All of this because her boyfriend skipped town?" The tone of disbelief was clear in her voice. She could feel the pain but she couldn't understand the source. Evangeline had graduated high school at sixteen with a full scholarship to Stanford but the busy schedule hadn't stopped her from dating. Though she had gone through her fair share of breakups, none had ever hurt like this.

"I know exactly how you feel Eva." Charlie sighed heavily over the line. "But as much as I hate to admit it, she was different with him. Things were really intense between them. Best thing to do now is wait I suppose. Let her work through this and help however we can."

She agreed with him then gave him a quick update on school. Her sophomore year was going very well so far and she had made some new friends. She told him about the birthday presents she had gotten from friends and thanked him for the camera he had sent her. He joked that their birthdays were easy because he only had to buy two of the same item. The two laughed together before saying goodbye. Bella and her sister had been getting the same gifts for their birthdays every year and the two had always loved it. Their personalities were so different that the twins didn't mind playing up their physical similarities.

Bella had always been shy, unsure, and content to stay inside whereas Evangeline was the opposite. She was outgoing, confident, and loved being active. This came in handy when trying to discern the two. Bella's hair, never getting a lot of sunshine, stayed brown but the extra rays had brightened her sister's locks into a gorgeous auburn color. Physical activity had also given Evangeline's body curves that were nonexistent on her sister. Bella also preferred her nickname but Evangeline hated having her name shortened by anyone but her family. These traits combined with their differing levels of outward confidence usually made it easy for close friends and family to tell the difference. Everyone else was left struggling to figure out who was who.

Neither girl knew how much these differences would mean nor how much their lives were going to change because of them.

A.N. I've had this story in my head for a while and I'm finally posting it online. Please review and let me know what you think! Also, I don't own any of the Twilight characters or story. Only my OC and my own ideas.
