Disclaimer: I don't own H2O. Love it though.

A/N: This is my first fanfiction and I hope you like it. Note this plays 25 years after season 2 and that it centers around Cleo's, Emma's and Rikki's daughters. Emma, Cleo and Rikki will play a minor roll, though.

Chapter 1: Encounter

"Hurry up, Amber or you will miss your plane," Rikki Bennett ordered. "I never agreed to go to that lame camp," her daughter objected as she came down the stairs with a cell phone in her hand. Her blond hair, which was just as curly as her mothers, was tied up in two braids. Amber wore a black skirt and a red tank top. "We discussed this a million times. You can't just sit around house the whole day playing with your computer," Rikki told her. "Why not?" Amber asked as she placed her backpack next to her small suitcase.

"There's more to life than surfing the net and chatting. What do you have against the Gold Coast anyway?" her mother replied. "One. I'm stuck in some camp like a five year old. Two. Melbourne is way cooler than the Gold Coast. Besides just because you couldn't have a computer as a teenager doesn't mean I have to give up mine," Amber listed and grabbed a bottle of water. "That's it. Hurry up. The cab is waiting," Rikki told her, a bit hurt. Amber opened the bottle, but the water burst out, spraying her and her mother with water. Rikki made a shocked face that she always had when she got surprisingly wet. "Calm down. It's just water," Amber said as she picked up her bag. Her mother regained her composure and muttered, "Right, just water. Well, have fun. Call me when you get there." "I will. Bye mom. Tell dad bye from me when he returns from his business trip," Amber told her, gave her mother a hug and then left her family's huge flat.

"Clothes, check. Phone, check. Books, check," a blond girl muttered as she looked through her neatly packed bag one last time and then closed it, "Perfect." She took her plane ticket and bag and went into the living room. "I'm ready," she said to her mother and father. "Have everything?" Emma Wilson asked her daughter. "I checked twice," Emily replied. "Then nothing can go wrong, sweetie. Have fun at camp," Ash Wilson said and gave his daughter a hug. "Have fun, Emily," Emma told her and also hugged her, "James is the car ready?" "Everything's ready," Emily's brother, James replied as he came in, "But it's raining like crazy."

The family brought Emily to the car under umbrellas. A few drops fell on Emma, but she didn't notice or care about them. "Call us when you get there," Emma said. "I will," Emily smiled as the car drove off and then turned to her brother, "Thanks for taking me to the airport." "No problem. I would do anything for my little sister," James replied. Her brother was three years older. "I'm your only sister," Emily reminded him as they entered the Canberra Airport. Emily Wilson said good bye to her brother and entered the airport. "I'm off to camp," she smiled as pushed a bit of her long straight hair out of her face.

"I can't wait!" a brunette cheered as she jumped through the bedroom. She was deciding what to wear. After nearly twenty minutes she decided for a pink top and a denim skirt. Checking her long, curly, brown hair one last time she went into the living room of the apartment. "Do you have everything, Sarah?" her mother Cleo Sertori asked. "I think so," Sarah answered as she picked up her bag. "How about your bus ticket or do you plan on walking from Brisbane to the Gold Coast?" Cleo laughed as she held it out. "Right. Sorry. I'm just so excited." "I hope you have fun," the mother said as she walked to the kitchen, "Four weeks at camp." Cleo began to wash as Sarah turned around one last time and hugged her mother. "I'll miss you," Sarah told her. "Same here."

Then Sarah left and went to the bus station. A long bus ride awaited her.

A few hours later Amber's plane had landed. For her the plane ride hadn't been so bad. She had flown first class after all. Now all she had to do was find the bus that would bring her to camp. Walking around the crowded Gold Coast Airport, she sighed.

Suddenly she ran into someone. A blond girl and a brunette also with bags. Meeting their eyes it felt like time stood still. An image of a cave and a pool flashed into their minds, along with a feeling of knowing it.

Snapping back into reality, the three girls muttered, "Sorry." Before they could go their ways, a woman came up to them and said, "You must be the last three girls. Amber, Sarah and Emily, right?" The girls nodded. "So you are Mrs. Rose, the councilor," Emily assumed. "That's right. Follow me. The bus is parked outside," the councilor replied and led the girls to the bus.

The girls boarded the bus and looked around. Five other teenagers were already there. They sat down on a bench next to another girl that seemed their age. The girl also had long blond hair and was very pretty. Her eyes were blue. "Hi, I'm Jessica Manden," the girl introduced herself. "I'm Emily Wilson," the blonde girl with blue eyes said. "My name is Sarah Sertori. Nice to meet you," the brown eyed brunette smiled. "I'm Amber Bennett," the curly blond told them, but then turned her attention to the scenery outside the bus. "I'm so excited," Sarah confessed to the girls. "Same here. I can't wait," Jessica agreed. "I'm also looking forward to camp," Emily said. "I have a deck of cards with me. You want to play?" Sarah asked. The two blonds nodded, but Amber declined. "What's up with her?" the three other girls wondered.

After a thirty minute bus ride the bus stopped in a parking lot. When the kids stepped outside they saw to their left the crystal blue ocean and on their right a path leading into the woods. "Up the path are your cabins, the mess hall and any other buildings. Cabins have already been assigned and there will be no changing," Mrs. Rose told them and then began to read the room assignments, "Cabin 5. Amber, Jessica, Sarah, and Emily." "Isn't this great?" Sarah asked. Emily and Jessica nodded while Amber rolled her eyes. After Mrs. Rose finished reading the assignments, she said, "I will remind you, that girls and boys are not allowed into the cabin of the opposite sex nor is any making out allowed. Any infractions to these rules will be punished severely. Now go get settled and we will meet at the shore at 5:30."

The teenagers scattered and began settle down. The girls entered their cabin and saw two bunk beds, two closets and a table. A window on the back wall gave them a view of the woods. "So who wants which bed?" Emily asked. "Mine," Amber said and sat down on one of the lower bunks. "If you don't mind I would like to have a top bunk," Sarah replied. "Me too," Jessica admitted. "Okay, I'm fine with a bottom bunk," Emily told them and with that the bed question had been settled.

They spent the rest of their time unpacking and then assembled at the beach at the appointed time. When everyone was here, Mrs. Rose told them, "For your first evening we have something special planned. See that island out there? That's Mako Island. We'll go exploring there. Now everyone board the boat."

On the boat Amber sat down next to a boy with brown hair. "Why go explore some dumb island?" he muttered. "Agreed. We could spend our time so much better," Amber replied, "I'm Amber." "Jordan. You were forced to come here as well?" he asked. "You could say that," she answered, happy she found someone who also didn't want to be here.

On the other side of the boat Sarah said, "Mako Island looks so beautiful." "It's been untouched for thousands of years," she heard someone say behind her. She turned around and saw a red haired boy. He had beautiful green eyes and a few freckles danced over his face. "You know a lot about Mako?" Sarah asked. "I grew up here so I guess I do." "Like what?" "Well, around Mako there are a lot of reefs where many fish and sharks are inhabited. Plus it has a some very rare underwater life. On top of that the volcano had been dormant for a long time as well." "Cool." "Oh, I'm Ryan," the redhead introduced himself and reached out his hand. "Sarah," she replied and shook it with a smile.

"I can't wait. Mako Island is supposed to be full of mysteries," Jessica said to Emily. "I've never heard of it, but it looks very nice," Emily replied, "You're into mysteries?" "Not only. I'm also into Biology. Marin biology. "

Arriving at Mako they got off the boat. A girl stood on the beach with her cell phone. "Damn it. No reception," the girl with red hair cursed. "What do you expect? We're miles from mainland," Amber replied. "That still doesn't explain it," the girl objected. "Yes it does. The connection doesn't reach this far out," Emily explained. "Riley, stop making a fool of yourself," Ryan told her. "You know her?" Sarah asked. "Unfortunately. This is my twin sister, Riley," he introduced. "Ow," Amber said. "You have a problem with me?" Riley asked. "No of course not," Amber answered, drenched in sarcasm. "Break it up, girls. Here are your maps. You will be with your roommates," Mrs. Rose told them.

They had been walking along the beach for a while now. Suddenly Amber, Sarah and Emily had an urge to walk more towards the island center. "Where are you going?" Jessica asked, hurrying after them, "Sarah! Emily! Amber! Wait up!" The three girls didn't react. They kept on walking through the woods.

When the urge finally let up, they were near a small waterfall. It was already getting dark. "What happened?" Emily asked. "No clue," Amber replied. "Where's Jessica?" Sarah questioned. "I think we lost her," Emily answered, concerned. "I think we are lost," Amber corrected her. "Doesn't matter, but we have to find the others before it gets dark," Sarah said and took a step forward.

Unfortunately there was a hole and she fell in. However Sarah held on to Emily, who held on to Amber so they all fell into the hole. They landed in a cave. "Great. Now we are not only lost, but stuck in a cave," Amber said. "Lets look around before we say we're doomed," Emily suggested. The girls nodded and walked through the cave.

They reached a bigger cave with a sort of pool in the middle. "I've seen this place before," the three girls thought, but didn't dare say it aloud. "This is the inside of the volcano," Emily said amazed, "And look there's tide rings and a hole in the wall underwater. That's our way out." "Ah… To be honest, I can't swim well," Sarah confessed. "I'll help you, but first I'll check how far it is until the ocean. I'm a pretty good swimmer," Emily replied and dove underwater. A while later she came back and told them, "It's about a twenty second swim under water." "Okay," Amber shrugged and jumped in. The girls looked at Sarah. "Maybe I'll stay here," she began uncomfortable. "And wait for a miracle? Come on, we'll help you," Amber replied as the blonds stretched out their hands. With a smile Sarah took them and jumped in.

Just as they were about to dive under the waxing moon came over the volcano entrance. It would be a week until it was full. Suddenly the water began to bubble and small yellow bubbles flew to the moon. The girls looked up at the moon and then themselves. "What's going on?" Sarah asked, scared. "I'm not sure," Emily answered, but then just as soon as the bubbles had started they were gone. "Weird," Amber muttered and the girls nodded in agreement. Then they dove under and swam out into the ocean.

A/N: Why did the moon pool activate without a full moon? What will happen to the girls now? How come Emma, Rikki and Cleo can touch the water without transforming? If you want to know keep reading. Please also review so I know that I won't put up the second chapter for nothing.
