I barely noticed as Jacob carefully plucked me off of his back and set me on my feet. The shock of what I was seeing had me frozen.

I just couldn't wrap my mind around it. I knew very little about my sister, but I was absolutely positive that she was about twice as old as I was. I knew she had brown hair like mine, and brown eyes like Mom's. And I knew that she had pretty much dropped off the face of the earth after her wedding.

I had to have it wrong. The person standing in front of me wasn't my sister. Maybe she was Nessie's sister. Maybe she had Bella's hair, and everything else was Edward's. That would mean Nessie had lied—again—when she'd said she was an only child. Oh, well. I'd already forgiven her for the lying.

But that didn't explain Rosalie's mysterious lack of aging, not to mention Edward's…

Edward. I looked back to him, sitting next to the person who might be my sister. He, for one, was impossible to mistake. The topaz eyes, that strange shade of bronze hair…no, that definitely couldn't be anyone else.

Slowly, cautiously, my possibly-sister stood up. Her gaze was fixed on Renesmee, who was now standing with one arm around Jacob's waist. She was looking back, waiting for a reaction.

"Renesmee Carlie Cullen," she said quietly, "what have you done?"

"Mom, she would have found out anyway. Jake and I just helped her along."

Nessie had called her 'Mom.'

She was shaking her head now, looking at Nessie with unreadable emotion in her eyes. "We didn't know that for certain. Even Alice didn't know…" Alice. Was Alice here, too?

"That's just because of me! Mom, she saw Rosalie in one of your wedding pictures. It doesn't take much to connect the dots."

Everyone looked a little shocked at this information. It was the blonde man at the other end of the table that answered first.

"When did she figure out?"

"Just now, I think. She came and asked me about it, so I told her I'd try to explain. She wants to know, and not much is going to stop her."

The blonde man spoke again: "But how did we—"

"—not know she was asking?" Nessie finished. "We lied, obviously. You can't be all-knowing all the time, you know." She grinned, and the tension seemed to relax just a little. I might have been imagining it, though.

"That still doesn't explain why she wants to know in the first place," Rosalie added, examining her fingernails.

I sighed, wishing they would quit talking about me like I wasn't right there. Besides, I was confused enough without listening to their conversation.

Edward suddenly chuckled a bit. It sounded like music.

"If you'd really like to know, you might try asking her yourself. She is standing right in front of us." Well, at least someone was on the same page as me. Or knew which page I was on, anyway.

"She sort of has a point, Sienna," Nessie told me. "Why are you so desperate to know?" Everyone looked at me expectantly.

Okay, now I was irked. "Shouldn't that be kind of obvious?" I asked. "I come all the way here from Florida to try to find my sister, only to meet her daughter, who tells me that she's in New Hampshire, and that I can't talk to her at all. Then I meet that daughter's 'cousin,' who somehow attended my sister's wedding eighteen years ago and looks exactly the same now as she did then. And, on top of all that, you all have some sort of dangerous secret that's driving me nuts, but that you won't give away! You're giving me reasons to be curious, and you want to know why I'm desperate to know?" I was practically shouting, and had to take a deep breath to get control of myself.

Edward raised an eyebrow. "Are you done?"

"For now…I think."

"Well, good," a voice said. It came from the direction of the kitchen. "It's about time we got to the happy family reunion part."

After every other unexplainable thing I'd seen tonight, I guess I shouldn't have been surprised when Alice Cullen entered the dining room, followed by a tall, gorgeous, muscular man with honey-blond hair. She, like the others, looked exactly the way she had in Bella's wedding pictures, except that her short, black hair was a spiky disarray on top of her head, instead of the sleek curls she'd been wearing on the day of the wedding.

She noticed my stare and gave me a friendly grin. "Hi! I'm Alice."

"Um…yeah," was my intelligent response. Jacob and Nessie both laughed.

I finally turned to Bella and found that she was looking at me, as well. There were so many things that were wrong, that didn't make sense…and yet there she was, right in front of me. My sister, the sister I'd come all the way to Forks, Washington to find.

"Is anyone going to explain what's going on?" I asked, not taking my eyes off of my sister. It was Bella who decided to respond.

"It really would be better for everyone if you didn't know."

I sighed. I had figured it would turn out that way.

Bella stepped carefully around the table, not taking her eyes from me, while everyone else remained frozen. Her movements were fluid and graceful, even with her caution. She stopped right in front of me.

"So, you're my sister, then?" she asked.

One side of my mouth tugged into a grin. "My name's Sienna."

"I know," she said, returning my small smile. She held out one pale, slender hand to me. My fingers cautiously made contact, and I gasped. Her hand was as cold as ice. But I held on, not wanting to seem disgusted, or afraid.

"You look a lot like my mom," she said quietly.

"Our mom," I reminded her.

"Yeah, our mom," she amended.

Suddenly and inexplicably, I grinned. Even she didn't deny it. This was really my sister. I threw my arms around her, giggling like a little girl. I ignored the fact that she felt like a solid slab of granite in my arms, not to mention that she was unnaturally cold.

She hesitated for a moment, as though she hadn't expected this, but I felt her cold arms slowly snake around me, holding me in a surprisingly gentle embrace.

And just like that, I was hugging Isabella Cullen, no longer a stranger, but a sister. My sister.

Okay, so there you have it! I know, you're all waiting for Sienna to find out, and she will...eventually. Soon, I promise. I meant for this chapter to be a bit longer, but you'll have a new one soon, I promise. Even I didn't think I could write this fast!

I have so far gotten eleven reviews for this chapter. ELEVEN!! Thanks to everyone who took the time to review, and especially to the people who wrote those really nice paragraphs and asked me questions. I like questions; they tell me what I'm leaving out :)

And now we come to the important part: the plot. There are two ways that this plot could go in my mind, but I don't want to tell you and spoil either of the surprises. So, here's what we'll do. Only one plot leads to a sequel, so if you'd like to see a sequel after this one is finished, please mention it in your review, or PM me, whatever. I know it seems a bit early to think about a sequel, but there are important things that need to happen starting after this chapter. I want to write the sequel, but if you don't want one, that's okay too.

So, please review. Thank you for reading, as well :)
