I do not own H2O, only a few people and ideas.

A/N: Well its been awhile since I've published one of these so i figured why not? This story has nothing to do with my older H2O stories, this is new. Please review and let me know what you think.

December 2007. Mako Island.

Fifteen-year-old Jack haled himself out of the round pool of water into a cave. Looking up, he took notice that he was below the island's volcanic crater. This didn't worry him much, as he had climbed around in caves before. Having just moved to Australia from the United States, he couldn't really understand the taboo the locals had about this island. Of what he had seen of it so far it looked to be rather amazing. Even the cave he was in now would be perfect hideout if you wanted to get away from the stresses of life.

Clicking on the flashlight he had brought with him, Jack looked around the cave. Outside, he could hear the rumble of a thunderstorm. Silently, he cursed himself for not dragging his boat onto the beach instead of anchoring it just off shore. Deciding against struggling through a storm, he slowly walked to the cave wall, studying it with the light from the flashlight.

The wall was made of volcanic stone, but he could feel something else, almost like a heartbeat coming from behind the stone. Slowly, cautiously, he raised his hand to touch the wall.

"What are you doing here?" came a dream like voice from behind him. Jack spun around, startled at the sudden appearance of another voice. A single girl, not looking much older then himself sat in the pool. She was beautiful by all standards, her long blonde hair flowing down into the water over her shoulders and the orange straps of a top that was hidden by the water. But her expression was hard, like she was angry.

"I'm just looking around is all," said Jack as he slowly approached the girl in the pool.

"This place is not yours, you must leave right now," said the girl as the water began to boil like it was a Jacuzzi. Jack knelt down on the edge of the pool and stared deep into her blue eyes.

"Don't you think you should get out of the water, I mean you could be burnt," he said. Her expression changed from anger, to shock, then back to anger.

Jack was surprised, because judging by the amount of water that was boiling, she should have been dead by now. Being an outcast, he couldn't seem to come up with anymore words then what he had said. He stared deep into her eyes and refused to look away, like he was trying to figure her out.

Slowly, the girl raised her hand out of the water and brushed Jack's cheek slightly. This caused him to blush as well, as he had no idea what was about to happen. Then she placed her three middle fingers on his forehead while pinching the bridge of his nose with her thumb and pinkie. Jack's body was suddenly rigid, and he was paralyzed and unable to move.

"What are you doing?" he asked with a slight panic. But the girl didn't answer. Rather she began to sing in a strange language he had never heard. He felt energy begin to flow out of her and into him. Images flashed before his eyes, to quick for him to comprehend. Finally, she released him. Jack felt flat on his back into the sand floor, suddenly tired from what had just happened. Sitting up slightly, he could see that the girl was looking at him, anger still burning in her eyes.

"You have seen to much, and so this is your punishment" she said before submerging and disappearing into the cave the led to the sea. Jack tried to call after her, to stand up and give pursuit, but he lost his balance and fell into the boiling moon pool.

Through a cloud of bubbles, he looked around the pool for a moment. But the water around the lower half of his body began to churn and boil. He watched with a combination of horror and fascination as his clothes disappeared and his legs began to merge together. After ten seconds, he found himself face to face with a reddish fish tail.

Jack shot out of the water like a missile, shouting and cursing as panic began to consume him. He clawed at the rocks around the pool as he attempted to pull himself out of the water, but the added weight of the tail only hindered his progress. Finally, he forced himself to relax as he looked back at the tail.

Looking up through the crater, he sighed and ran his fingers through his hair, wondering what he was going to do.
