CHAPTER 1

Will's POV:

I dipped beneath the waves, Bella close behind me. I loved swimming with her; it was like something out of a fairytale, the mortal with the mermaid swimming side by side. I loved the ocean no matter what, but everything seemed to be even more beautiful when she was around.

We were out near Mako and on our way back to the moon pool at the moment. I turned to look at Bella and she motioned at a colorful fish that was just swimming past. We swam through a small forest of coral and compared the seashells we found on the ocean floor. I had to go up frequently for air, but Bella remained underwater, still searching for shells. As she swam along the ocean floor, I tried to imitate the smooth and fluid motions of her tail and body. I would never be perfect, but Bella had to be the best diving coach ever. To bad I could never share my secret with anyone. I couldn't very well tell them I had a mermaid for my coach. A school of fish swam by at just that moment and Bella and I stopped to watch them pass. As I turned my gaze to the fish, I didn't notice the even bigger fish that was slowly approaching from behind, following the school.

I suddenly felt Bella's hand on my arm, her nails digging into my skin. I spun around in surprise; only to come face to face with a long torpedo shaped shark. Apparently Bella and I had come between him and his lunch. From what I knew about sharks, that meant we could be in serious trouble. I froze in place, not take my eyes of the animal. Bella still had her hand on my arm and I moved out of instinct in front of her. The shark seemed to be sizing us up, and I took that opportunity to start moving backwards, both of my arms wrapped around Bella by this time. Then our pleasant swim turned into a nightmare as the shark moved and began to circle us.

I had to think fast. I looked at Bella out of the corner of my eyes and motioned for her to go. I knew that she could swim away in an instant; I just wanted her safe. She looked at me like I was insane and shook her head firmly. I turned completely in her direction this time and attempted to convince her, but my motion must have startled the shark, and he closed in before I even knew what was happening. I felt a rush of water as the shark lunged at me, but I didn't feel any pain. I looked around, praying that Bella was gone, but then I saw her focusing her powers on the shark. The animal seemed confused and swished his tail nervously. It was only then that I noticed the small trickle of blood that was beginning to ooze out of my arm. This wasn't good. I needed to get out of the water NOW, but I was afraid to move fro fear of startling the shark. As I was debating with myself what on earth I was going to do, Bella swam slowly over to where I was, all the time still keeping her powers directed at the shark. The large fish seemed to be contemplating whether or not to charge. Bella flicked her wrist sharply and the shark shuddered and turned away. I breathed a sigh of relieve as it swam away and disappeared into the distance. I began to surface; I was in desperate need of oxygen. Rather than staying below like she often did, Bella joined me at the surface even though I was sure that she didn't need the air.

"Oh my gosh, are you okay?" she cried the minute we reached the surface. I glanced down at my arm, it looked worse than it had underwater; it was bleeding profusely and now there was no water to wash the blood away.

"It's nothing, just a scratch," I lied. She didn't look convinced.

"Look, we need to get you out of the water now. The moon pool is only a few minutes away, even swimming at normal speed. Do you think you can make it that far?" She asked worriedly.

"I think I'm going to have to," I said, "but I might need a little help."

She nodded, "No problem, just stop me when you feel like you can't go any further by yourself, okay?"

I nodded, "right," I said, "now let's go, the blood might attract the shark again and we don't know if your powers will scare it off a second time."

With that we dived back under again, Bella swimming next to me slowly as we cautiously made our way towards the moon pool. I was actually able to go most of the way by myself, I guess the salt water was good for my arm, I didn't know. We swam into the cavern and surfaced. I climbed out of the moon pool immediately and Bella soon followed, although it took her a little while because I couldn't really help her. When she finally succeeded in pulling herself out onto the sand, she flipped her wet hair over her shoulder.

"I don't usually like to do this," she said, "but I need to get dry fast." And with that she turned her hand over her body, turning all the water into jelly. Then she began to brush it off. In about a minute she was on her feet, something that usually took anywhere from ten to fifteen minutes, sometimes longer if there weren't any towels available. She knelt beside me on the sand.

"Let me see it," she said softly, motioning for my arm that I was cradling in my hand. I grimaced, but let her see. It actually wasn't that bad; it looked worse than it was, but it hurt like crazy, and it was still bleeding.

She gasped when she saw it, but didn't freak out like I had expected.

"Okay, first we need something to stop the bleeding" she said practically, pulling herself together. I was glad someone was calm, cause I was still a bit shaky after everything. She was looking around the cave as I spoke.

"Here, this should do," she said, returning with a cloth; I think it was a T-shirt, I didn't know. It was pretty thin and she had no problem ripping it in two pieces, one was quit a bit bigger than the other. She dipped the end of the smaller piece in the moon pool, being very careful not to get wet herself, and used it to gently clean the gash. I gasped at the sting left by the cold water. She stopped immediately.

"I'm sorry," she apologized, but I shook my head.

"No, it's fine, I can handle it. Go ahead." I gritted my teeth as she proceeded to finish cleaning the wound. Finally she was done and had wrapped the other piece around the gash, securing it tightly.

"It's not the best bandage ever," she said, sitting down beside me, "but it'll do for now."

"It's fine sweetie." I said, putting my good arm around her. "Whatever it was you found was perfect; where was it anyway?"

She thought for a second. "It was over there, in a nook or something." She stood up and went back to the other side of the cave.

"Yeah, it was…" her voice trailed off, "Right here…" She went silent.

"Bella?" She was just staring at the walls.

"Hey," I said, getting up and coming over to stand beside her, "everything okay?"

She didn't answer.

"Bella? Earth to Bella," I teased, waving my good hand in front of her face. Then I noticed how serious she looked, and I stopped smiling.

"Is something wrong?" I asked again. She shook her head.

"Someone's been here." She said shakily, gesturing towards the wall. I followed her gaze and studied the wall. My eyes rested on a small carry-on bag inside just one of the many nooks and crannies that filled the place. There was a thermos next to it.

"That wasn't here yesterday," I said slowly, turning to look at her. She looked scared.

"That's where I got the T-Shirt; it was just lying there and I grabbed it."

I shrugged, "Maybe it belongs to Zane?" She looked at me.

"Zane's in Sydney with his father, remember? He left two days ago, Lewis isn't due for a vacation for weeks, and that doesn't look like it belongs to one of the girls. Besides, I don't think any of them have been here since last night anyway."

I knew how serious this could be, but I didn't want Bella to know how freaked out I was getting. I tried to act nonchalant.

"So, someone's been here, relax. It doesn't mean that they know anything. Remember, I was here once, and I actually SAW something, and I still couldn't figure it out on my own."

I was trying to convince myself as well as Bella that everything was fine, but it obviously wasn't working. She looked upset and I didn't know what to do about it, so I did the only thing I could think of. I put my arm around her shoulders and squeezed them comfortingly, planting a light kiss on her forehead.

"Take it easy, I'm sure it's nothing. But just to be on the safe side I wouldn't come here for the next few days. Let me come and check things out." She looked up at me, the concern on her face growing. I jumped to cover myself, "

I'm not saying that there's anything to worry about," I added quickly, "but just in case, I don't want anything to happen to you. Okay?"

She nodded, "You're right; I'll tell the girls too. Do you think we should look inside the bag?" She asked.

"Yeah, I think so, maybe it will give us a clue as to who's been here, or at least what they want anyway." I said, stepping forward. As I did, I jarred my arm a little bit.

"Ahh!" I gasped, holding it to my chest. Bella was at my side in an instant.

"You know what, forget the bag, we need to get you back to the mainland. If I help you, do you think you can make it back?"

I nodded, "Yeah, but we'd better leave now, if my arm starts bleeding again it won't be safe. Just promise me that you won't come back to look at that bag without me, okay?"

"Okay, okay, now lets go," she said in a rush. I wasn't completely satisfied with that answer, but I knew that waiting around any longer would be foolish. We slipped back into the moon pool. While she was transforming, I turned and took a hard look at the nook in the cave. A dozen questions were running through my mind. Who had been in here? What on earth did they want? And more importantly, how much did they know? Yes, I was curious, but I was also a bit scared to find out the answers.

A/N: Okay, there was the first chapter. The whole shark thing was just an intro, but I had a lot of fun writing it, as sharks are one of my favorite animals. I know a few of you were waiting for a sequel so here it is! Did you like it? Did you hate it? Please review and tell me! Oh, and credit for the disclaimers goes to my BFF Sylvia, she hates it when all I put is "I don't own H2O". :) Anyway, thank you so much for reading! Love you guys! :)
