This story is meant to transition from season/series 2 into 3. I hope to cover all the changes that occur within their worlds during this time. The Characters of Leda, Stephanie, Rachel, Melinda and Mat are my own characters whom are based off of real people that are friends of mine (all of whom think it is cool that I'm using them in this story). The character of Ian is also mine and based off of me. All names for these characters have changed from real life. I have almost five chapters complete and ready to type and a time table set for their publishing. I welcome feedback and encourage you to try and convince me to speed up my timetable. So please read and if you feel up to it; review it and tell me what you think.

Warning: My prologue and first chapter may be kinda boring, but I feel it is essential as it establishes a base for Bella as to her mind set throughout this story.

Warning: My prologue is the opening scene to S3E1 so it is basically a giant spoiler, and the other half of it is a recap of seasons/series 1 and 2. Now I do realize it may be hard to follow, it is just the style I wanted it in and I can not really explain why I wanted that it like that so sorry if it is confusing.

Disclaimer: I do not own H2O: Just add water. Unless otherwise noted I do not own any of the characters.

Prologue

.

It was a bright sunny summer day. The beach was crowded with people of all ages. School was out of session and before long would be starting back up for a new year soon adding to the reason to be out enjoying the beautiful day that they had. Amongst the crowd two girls walked side by side well up on the beach beyond the reach of the tide. As they walked they didn't take note of anyone in particular that they passed by. But one of the other girls at the beach took note of them as they approached.

.

I don't know what it was about them that drew my attention but I knew something about them just wasn't normal; they were different from ordinary girls and while I didn't know what it was then I just knew something was different about them. I was new to the area and felt out of place and here were these two girls that had stood out to me; I kept a watch on them and as my suspicions grew I began to piece the puzzle together.

.

The two girls hadn't bothered to take note of her as they approached her. When some of the guys in the water sitting on their surf boards started to heckle her and harass her with cat calls the two girls looked to each other and grinned as they silently decided to teach the guys a lesson in how to treat a lady.

.

.

They were not ordinary girls; their adventure had begun nearly two years ago. A local boy had crossed a new girl at school and she had made it her personal mission to mess with him in an attempt to teach him a lesson. She had stolen the spark plug from the engine of his small watercraft and upon discovering the missing part he decided to make the best of the situation, and lured a girl walking by into getting into the boat as he set it adrift. Rescued by the spark plug thief they took the craft for a ride. When the girl who had been the target of the prank turned hijacking spotted a friend of hers she and her now co-culprit invited her along and the three girls took the small craft out onto the open waters only to run out of gas while out in the middle of nowhere.

Forced to paddle to nearby Mako Island they found themselves exploring the island trying to get a cell signal. Fate took them into a small cavern with a pool of water that had an underwater entrance connected to the ocean. By time they had discovered the pool it was late at night and as they got into the water -having finally decided to swim out through the underwater entrance- the full moon passed overhead. The cavern that they were in was the cone of a dormant volcano and as the light form the full moon shown down in onto the water it began to bubble and sparks of light glittered in the air as bubbles rose up towards the sky.

The next morning they each discovered that their worlds as they knew them had changed. The next four months saw them embrace what had happened to it and the consequences that came with it. When faced with the fact that a scientist had learned about them and planned to expose, exploit and study them they were forced to give up the secret they had been keeping with the help of a lunar eclipse. Or so they thought.

The next day they learned that they had unknowingly tricked the scientist into believing that they had given up their secret and no longer possessed it and were once again ordinary girls. To their surprise they had only lost their special secret for 12 hours and that they still possessed their special secret after all.

The next four months left them living their lives just the same as they had before the trouble with the scientist. The full moon was a dangerous foe for them and just when they felt safe they found that their secret had a new twist to it and their worlds were once more turned upside down. With their world suddenly changing on them (with the new twists to their secret and their real world troubles) they dealt with events as best they could until a new girl in town started getting close to their secret. Troubles really started and took a disastrous turn for the worse when she discovered the secret of Mako Island's Moon Pool; she too now shared in the secret. Believing the secret was meant for her alone she sought to drive a wall between the girls their friend who had known their secret since almost the beginning (whom she also happened to be dating at the time). When a big play to drive them apart failed she found that it was between her and the girls that wall had been driven with her boyfriend the one trapped in the middle. Deceiving him with lies and trickery she drew him in but overplayed her hand and once exposed delivered him an ultimatum; them or her.

Choosing his friends he broke off his relationship with her driving her to seek out revenge. At the next full moon the girls were lured into a trap by their new foe and faced off with her; the losing side of the battle would no longer be part of the secret for good (not a temporary effect like with the scientist and the lunar eclipse). With the three friends emerging victorious they returned to their lives.

The months continued and at the end of academic term they said goodbye to one of their friends as she left with her parents to travel the world. But all was not lost for new changes were in store; new dangers and new friends.

Keeping her hand held low at her waist one girl began clenching her hand into a fist, curling her fingers in as the water around the guys began to heat and bubble. Then with her hand kept low at her waist also the second girl twisted her wrist and the water beneath one of the boards jetted up enough to cause the board to roll dumping its rider. His buddies had a good laugh at his expense as did the two girls though not as loudly.

.

"Don't you just love summer holidays?" The first girl commented to her companion. And then they continued on their way unaware that the girl they were about to pass had seen the scene unfold and knew something wasn't normal.

.

I saw the water bubble and the board suddenly overturn. I also had seen them standing still looking out at the water as it happened. They had tried to be subtle and hide their actions, but when you've got a secret and suspect that there may be others that have the same one, you tend to take notice of these things.

.

The two girls continued on their way not taking note as they passed the on looking girl. After they were past she turned to look one more time at them. Puzzled by what she had just witnessed a multitude of thoughts went through her head.

.

I couldn't say with certainty, but I felt very strongly that they were hiding something; that they were hiding that they too were mermaids. I suspected there could be other magical places like the cave in Ireland but I had never found another place that had the same magic. Things would soon take an interesting turn, I was about to make a couple of friends that I could share my secret with.
