A/N: Please don't disrespect my character. I'm posting this for my own personal enjoyment and with hope that someone likes it. If you don't like my story, don't give me a bad review. I'm worried about this one because I'm writing a FanFic for the second biggest genre in the book category so please be kind to me. Thank you.

Yes, this takes place during Breaking Dawn so just imagine Gwen into everything. Since there will be a new character, please don't rag on me for there being some differences from the book. I'm trying my best from memory because it's been awhile since I've sat down and read it.

Okay so enough with the begging and pleading-on to the story!

P.S. Gwen's story will be explained in later chapters, so please be patient.

Blood Moon

BOOK ONE: Gwen

Preface

I stood in the field with my family, the people I loved most. I felt something warm squeeze my hand and I looked up to see Seth's brown eyes boring down on mine. He leaned down, pressed his scalding lips to my forehead and I felt a little better, not just because of the extra push of calm Jasper gave me.

I turned my gaze past Bella and Edward, who stood side-by-side, holding Renesmee. Past Carlisle and Esme, past Emmett, Rosalie, Jasper, and Alice. Past the wolves and onward out onto the field, where the Volturi stood. All of them.

I gulped and Seth squeezed my hand again, his eyes never wavering from Alec. I knew that once the fighting began, he'd go straight for him as I'd go for Jane.

Jane and I were fair game to each other, considering our powers were so similar. I knew she was jealous of me because I not only had the ability to cause pain but I had the power of her brother as well and that was enough to make her angry with me.

I knew Bella was pushing out her shield the best she could but it wouldn't hold for much longer and then the war would begin.

And I knew that it would be starting soon.

Chapter 1: The Occasion

Alice threw me into the room, tossing my bridesmaid gown behind me. "Gwendolyn, you better be dressed in 2 minutes because, so help me God, I will not let you ruin Bella and Edward's wedding." She grinned and I wasn't sure if she was serious about her threat or not.

I rolled my eyes at my sister, smiling softly. "Please. I respect my life too much to ruin today for those two. I'm just as happy as they are." I said, shutting the door behind Alice.

I slid off my skinny jeans and T-shirt, pulling the beautiful silver gown over my head. I reached around the back and zipped it up, since Bella and Alice had suggested that Rose, Alice, and myself wear the same color dress but of different styles. Rose got the halter-top; Alice got the simple spaghetti straps, and me? I got the strapless. Why? Ask Alice because apparently she saw something that I didn't. And that was me in a strapless bridesmaid dress.

Alice had already done my hair in a pretty up-do, with little bronze curls falling around my face. I stared at myself in the mirror of my room, my hand reaching up to touch the necklace I wore, the one I always wore.

It was a simple silver chain that had two elegant rings on it: the wedding rings of my birth parents. Since Edward and I had the same birth parents, he allowed me to keep their rings, as a token of my past life. I closed my eyes and sighed, trying not to think about my past on today, of all days.

The day my vampire brother married a human.

I absolutely adored Bella. If she made Edward happy, she could've had two heads and an extra foot for all I cared. It was about time to see my older brother happy.

Alice knocked on my door again and opened it before I could say anything. She gasped softly, seeing me in my dress and I smiled at her, seeing her in the dress she had picked out for herself.

"Well, you look incredibly cute, Gwen." She giggled, throwing her arms around me in a hug.

I chuckled, hugging my sister back and her spikes tickled my cheek. We heard another knock on the door and Emmett poked his head in, grinning. "Hey, sis. You ready?"

Since Rosalie would be playing the wedding march on Edward's piano and Emmett was in Ed's side of the wedding, I'd be walking down the aisle (not really) with my biggest brother. I nodded and he held out his arm, and I slipped my arm through it. Just as we were walking out into the hallway, I saw Bella step out of Alice's massive bathroom, looking extremely beautiful and I knew I would've cried if I could.

"Bella…" I whispered and she turned to see me, before breaking out in a nervous smile. I let go of Emmett to step forward to hug my almost-sister, whispering "Go get him" in her ear. She smiled softly before taking her father's arm and waiting near the beginning of the hallway. Jasper and Alice stepped forward, making their slow decent down the huge winding staircase to the spacious living room below, where the people of Forks were waiting. Emmett and I stepped forward and we began slowly down the stairs, before separating at the end of the aisle.

I found my brother's eyes and I nodded at him, giving him a knowing smile and trying not to think about his bride-to-be so once he saw her, it'd be a complete surprise. I stood beside Alice on Bella's side and my eyes started to wander the crowd. I saw kids from school, people that worked in town, and the few Quileute that showed up.

Before Rose started playing the wedding march, my eyes scanned the crowd of Quileute on Bella's side of the crowd. Billy Black, Jacob's father was there with Sue Clearwater and her two children, Leah and Seth. Leah looked like she'd rather be anywhere else, which was probably true but Seth was staring straight at me.

There was a moment when we locked eyes and the intensity in his dark eyes made me gasp a little. Alice looked at me for a moment and I shook my head barely, telling her nothing was wrong, without loosing Seth's eyes.

When Rose finally started playing the march, Seth and I broke eye contact as everyone stood and Bella's mother blocked my view of him.

Before I could think much of our little staring game, my eyes found themselves at the top of the stairs, where Bella stood in her white dress, on her father's arm as they slowly began the trek down our massive staircase. Gasps were heard from across the room and I smiled at my brother, who didn't even notice because his gaze was locked on Bella.

As she came closer to me, I noticed she wasn't looking at anyone else but Edward and the blush that filled her cheeks made me burst out in a grin.

Once she reached Edward, he took a step forward, holding out his hand, where Chief Swan placed Bella's small hand in my brother's. Charlie nodded once at Edward before going over to sit by Renee and her new husband.

The vows were very simple and I tried to not smile when they said "As long as they both shall live", a small change that had made since Bella would become one of us soon.

"You may not kiss the bride." I was vaguely aware of Mr. Weber saying those binding words when I finally glance back at Seth, who wasn't looking at my brother and Bella like he was supposed to be.

He was staring dead at me.

This puzzled me as I looked away, just as Edward and Bella's lips touched in a passionate kiss, which got broken up by Jazz and Em by the hoot they let out so immaturely. Why was one of the werewolves from the reservation so interested in me on Bella's wedding day? Maybe it was just me but I thought it was very odd-and a tad disrespectful-to be so engrossed at a bridesmaid when you're here for the actual bride's wedding.

I tried not to think about it as everyone flowed outside, where the sun had just set (perfect timing for us vampires) to begin the reception. A wooden carpet-like roll had been rolled out as a dance floor, with tables settled all around it, white tablecloths dangling in the light breeze.

Emmett and I walked out side-by-side to begin the traditional first dance with Ed and Bella, Jazz and Alice. Em grinned at me before placing a hand on the small of my back and taking one of mine in his massive other hand. I placed my free hand on his shoulder and we began to twirl gracefully.

"So what's bugging you, little sister? Ed's spotlight bugging you?" Em whispered and I rolled my eyes.

"Hardly." I said sarcastically and I almost blurted out what I was truly thinking of-Seth Clearwater.

I know I must sound severally stalkerish but there was something about the look in his eyes that had caused me to start wondering. It was almost like I had seen it before but I couldn't place it…

Once the first song ended and the crowd erupted into applause, Em kissed my forehead and I rolled my eyes, hating how he played up the baby sister act. As Bella went to start dancing with Jasper, Edward came over to me, holding out his hand. I took it, grinning at my big brother.

"Congratulations, Ed." I said as we spun.

He smiled, his eyes finding Bella through the wrung of couples that had started twirling as well. "Thank you, Gwen." He turned his eyes back to mine and his tone got serious. "Not tell me what's really bothering you."

I raised my eyebrows before remembering that he had probably heard my thoughts about Seth, which was confirmed by the nod Ed gave me. I played the moments back in my head, letting Ed see them in his own mind. He nodded when I was finishing, looking down at me.

"Well, I could check up on Seth's thoughts if it's bothering you that badly." Ed said thoughtfully and I shook my head.

"No, it's fine." I replied, glancing over at where Billy sat in his wheelchair, Sue pushing him around with her, her two kids following her. Seth glanced over at that moment we locked eyes again.

Ed gasped a little bit and that was what broke my concentration from Seth and I looked back at my brother who had a distant look in his eye. "Ed? What's wrong?" I demanded and he shook his head, coming back to reality.

"Nothing, Gwen. Nothing at all." He gave me a tight smile as the song ended, kissing the top of my head before going to dance with Alice.

I walked over to the table where Esme and Carlisle sat; chatting with Renee and her new husband, Phil. "Hello," I said, smiling shyly and they all looked up at me.

"Ah, Renee, Phil, I don't believe you to haven't met our youngest daughter, Gwendolyn." Carlisle smiled at me and I shook hands with my in-laws.

"Hello," I said again, grinning. "Pleasure to meet you."

Renee smiled, glancing from me to my brother, who was now twirling with Rosalie. "Wow, the resemblance between you and Edward is amazing."

I smiled softly, sitting down in the extra seat beside Esme. "That's because Edward and I are birth siblings. We were adopted together by Carlisle and Esme." I gestured to my parents and they both smile at me.

"Oh, that's good." Renee smiled, obviously trying not to say the wrong thing. I nodded and I thanked Carlisle mentally when he changed the subject, asking her about Florida.

My eyes trailed over the crowd of people laughing and having a good time in our backyard, dancing or just standing around. I found Billy again, with Sue and Leah, but Seth was nowhere in sight, causing me to purse my lips in wonder when I felt a hand touch my shoulder.

I looked up to see him standing there, smiling at me and I couldn't help but grin back.

"Um, hello." He said shyly. "I'm Seth Clearwater, Jake's friend." He held out his hand and I shook it, smiling.

"Gwendolyn Cullen." I replied, nodding at Edward, who was now spinning with Bella. "Edward's sister."

He gave me a knowing smile and I wink, saying that he knew who I was and I thought Well, of course you do. We only faught off an onslaught this past summer with your pack.

"I was wondering if you'd like to dance with me." He said quietly, gesturing with his other hand to the dance floor, where couples were dancing to a slow song, which I registered as Never Say Never by The Fray. It was then I noticed that I was still holding his hand and I nodded, standing up for him to lead me onto the dance floor.

He led me into the middle, in between Alice and Jazz, and Edward and Bella. He placed his hands on my hips and I rested mine on his shoulders.

I laughed quietly. "Nice job playing up the whole 'We've never met before' in front of Renee and Phil."

Seth quirked his mouth up in a crooked smile. "Thank you." He whispered and he started to sway.

I looked down, biting my lip before looking back up into his warm, black eyes. "You haven't heard from him, have you?"

Seth glanced over at Bella before shaking his head. "Actually, we've been getting his thoughts when we phase, so we know he's constantly in wolf form. We just haven't wanted to tell Bella that he's dead set against coming back."

"Oh" I uttered and I looked over at Bella, who was smiling and enjoying her wedding night. "I see why you don't want to tell her now…She'd be heartbroken on the best night of her life."

He shrugged under my hands. "Edward greatly appreciates it."

"I do, too." I whispered and we locked eyes for about the fifth time that night. I broke the awkward silence. "So…how're things on the rez? Everything going well?"

Seth smiled and nodded. "Things are going great, actually. School's getting ready to start back up again-Yay."

I giggled. "I know how you feel. I've gone through my junior year about 50 times now." I thought it was funny but there was that awkward silence again. "Um…ha-ha?" I offered and Seth chuckled.

"Okay, it was kinda funny, I'll give you that." He said, grinning at me.

I nodded, laughing again. "Good."

When the song ended, Seth slowly released my waist and I was about to smile at him before walking away when he leaned down and his scalding lips brushed my cheek, whispering "See you," before he was gone.

I stood there gaping for about a minute before Alice grabbed my arm, pulling me off to the side. "What was that?" She demanded quietly, leading me into the empty house.

"I-I don't know." I stuttered. "He just asked me to dance and we were doing fine but the k-kiss…" I trailed off, not knowing exactly what I thought.

Jasper walked into the kitchen then, seeing how tense Alice was before asking "What's going on?"

"Seth Clearwater just kissed my cheek." I whispered and he grinned.

"Aw, come on. Are you two gonna 'dish' about it now?" Jazz twanged sarcastically, which earned an eye-roll from both Alice and me.

"No, Jazz." Alice replied tensely. "If she involves herself with Seth, I won't be able to see her."

Now Jazz tensed up and I gulped a little, my eyes widening. I hadn't even thought about Alice's visions. With the Volturi probably watching us, it wasn't a good idea I went AWAL while we were being hunted.

We went back outside and I tried to enjoy the rest of the reception, dancing with Carlisle and Jazz, but my mind was always focused on one thing: Seth.

Before, I hadn't thought anything bad about the possibility of him liking me but now that Alice made it clear that she wouldn't be able to see me, I wasn't sure what I felt.

The spot on my cheek that he had kissed felt like it was burning now and I knew it wasn't because I was angry. I had enjoyed it, loved it even. But that didn't mean it was safe for me. I dreaded the thought of telling him we couldn't even start getting closer, just as friends, because my life could be in danger.

I noticed Bella, Edward, and Seth all gone when my hearing picked up on something. I stood by the back door and drowned out the music and the talking, focusing on what was coming from the woods behind the house.

"Take your hands off her!" I heard Edward snarl and I felt my face drop. Something was wrong.

I started down the small hill towards the trees and I could hear better.

"Yeah, bro, back away. You're losing it." Seth's voice made me squash my eyebrows together on my forehead and I finally rounded the first tree and the scene before me made me gasp.

Jacob Black stood, gripping Bella's arms in his hands, an angry expression his face. Seth stood next to him, his hand on Jake's shaking shoulder and I knew that Bella was in immense danger. My brother stood across from them, snarling under his breath, hands clenched into fists at his sides and I knew something needed to be done.

I closed my eyes and thrust my hands forward before I heard Jake shout "Ow!" and let Bella go, who was immediately in Edward's arms.

Jake turned to glare at me and he growled, deep in his chest. "You leech! Did you just use your power on me?"

I put my hands on my hips and stared him down, seeing Seth tighten his hand on Jake's shoulder. "You wouldn't let go of my sister and you were hurting her. Something had to be done quietly, Jacob."

He snarled again. "Well, keep your freakish, bloodsucker mind games away from me."

Seth stepped in front of him, shoving Jacob back. "Hey! Don't you dare talk about her like that, Jake! You were hurting Bella and you know it!"

I was surprised at Seth's outburst but I walked up and laid a hand on his shaking arm, seeing he was just as agitated as Jacob. "Seth," I whispered and he looked down at me, the shaking stopping almost immediately and I gulped again, that uneasy feeling tangling in my mind.

Seth shoved Jake one last time before two huge wolves stepped out of the trees, hidden from the party by the darkness. I noticed the big black one, Sam, and a gray one, Paul. The put their heads against the shaking Jacob's chest and pushed, forcing him into the darkness of the woods before I heard a ripping sound and the sound of paws running off.

Edward put a hand on Seth's shoulder. "Thank you, Seth, for coming down here when you knew something was wrong." Then Ed looked at me. "You, too, Gwen." He turned Bella back around and the two of them walked back up to the party, where I heard Emmett hoot like they snuck off together when he very well knew what happened. But at least it was a good cover.

I turned back to Seth and sighed. "I thought you said he wasn't here."

Seth shrugged, rubbing the back of his head. "I kinda wanted to keep it a surprise from everyone so Bella wouldn't have a clue. Sorry, Gwen."

I tried not to focus on the way he said my name, Alice's worried face floating through my mind. "Maybe we should get back to the party." I suggested and he nodded. I started to turn around but Seth's hand caught my wrist, turning me back around.

"Hey, are you okay? You're acting like something's wrong…" He whispered and I shrugged my bare shoulders.

"I'm fine." I assured him. I hated lying to him but it was the best thing I could do right now.

He sighed, sliding his hand down to twine his fingers through mine and I bit my lip, almost tugging away but I decided against it, letting him walk me up the hill, my hand in his.

When the reception finally came to a close and Bella was changed in her new outfit, everyone gathered on the front porch, rice in hand, to chuck at my new sister and my brother when the came outside. I shot some at Edward with Em and Jazz, who both laughed as it all hit Ed's back as he put Bella in the car before running around to other side to get in himself.

Seth smiled as they drove off, squeezing my hand before leaning down to kiss my cheek again, letting his lips linger for a moment before he turned with his sister, running off the steps and down to the trees.

Just as I heard Ed rev the engine more, I know he was trying to drown out the loud howl that came from Jacob somewhere in the woods.

A/N: WHEW! So? How was it? Like I said in the other A/N, I'm trying to stick to the book as close as I can so I've got it beside me as we speak ^.^ Yes, most of my chapters will follow the book fairly well but not all of them will be in this story, I promise

Thank you so much for reading! R&R
