"Aubrey I don't think we should be out here, it's not safe." Stacie says walking up another level of a very rocky path.

"It's fine people come here to hike all the time and look we've come this far we might aswell keep going right?" Aubrey says who was a lot further up on the path than Stacie was.

"Right" she says huffing at her.

"I'm going to go ahead you're kinda slow today" Aubrey says before she rushes off ahead of her leaving her alone.

"Great as if I even wanted to come here in the first place." She stops where she is fed up at Aubrey.

She hears the sounds of rocks moving below. She moves closer to where the sounds were coming from; confused by it she didn't know anyone else was even there. She sees a girl that she recognised from school. She leans downs and lends out her hand helping her to get up, which she reluctantly takes.

"You're Beca right? I've been meaning to say hi to you at school but err yeah sorry I kinda didn't." She says nervously to her not quite sure how to talk to the girl.

"Yeah it is. It's cool I didn't say hi to you either." She says walking past Stacie. "You coming?" She turns her head towards Stacie inviting her to come with her.

"Uhu" she starts walking again catching up to Beca. It's not long until they catch up to where Aubrey had gotten to.

"I thought you were following me. Why is she with you?" She says in a snide way as soon as she spots Beca there with Stacie.

"Nice to see you too Aubrey." She says sarcastically

Aubrey starts walking off not even thinking about waiting for them but they follow not too far behind until they come to a point that they can't simply walk over.

"What do we do now?" Stacie says in a really whiny tone.

"We could jump over; it doesn't look that far over." Beca says looking at the distance seeing it's not that big a jump. She moves forward so she is on the edge of it and leaps over to the other side landing perfectly.

"Come on it's easy" she says just as Aubrey steps forward and takes the jump herself. Bursting into laughter at how she landed right to Beca pushing her backwards slightly when she jumped.

"Come on Stace it's easy." Beca says seeing Stacie standing really far away from the edge not wanting to jump at all.

"Nope I can't do it, I'll fall and hurt myself and it's all slippery. Nope I'm not doing it." She says seeing that the edge was wet and not wanting to risk the jump at all.

"Come on we both did it and trust me it's not that far to jump at all." Aubrey says trying to assure her it's okay to do it.

"Okay fine" Stacie moves forward to jump and slips falling down a hole, screaming the entire way down and landing in a pit of sand.

"Oh my god Stacie are you okay?" The girls ask looking down the hole trying to see her.

"I'm okay, just get me outta here." She says looking around this tiny area that seemed like a cave.

"What should we do?" Aubrey asks looking to Beca hoping she's actually going to be some sort of help.

"I don't know call someone" she says sounding so unenthusiastic about being asked to help out. Aubrey leans forward more hoping to look for a way to get her out and falls face first down the hole landing right on Stacie. She moves off her and sits next to her seeing she was clenching her ankle.

"You okay?" She asks sounds worried about her.

"Yeah I think I twisted my ankle a little bit but I'm okay." She says looking round to Aubrey while still having her hand wrapped round her ankle.

"Beca you gotta help get us outta here." Aubrey yells up to her looking round seeing the tight space they were now in.

"Yeah and how can I do that?" She says sounding fed up of Aubrey being like that to her.

"Throw a rope down or something I don't know just help us get out." Aubrey yells back up this game was getting boring to her now. Before she knows it Beca slides down the hole and joins them down there in that small cave landing millimetres away from Stacie's foot.

"Now what?" Stacie says putting her head in her knees thinking they were screwed if all three of them were stuck down there.

"There's a light over there that's most likely the way out." Beca says seeing the light behind her. She turns back and looks directly to Stacie seeing how she was acting. "Stop being over dramatic."

The girls all get up and walk towards where the light is. The light wasn't an ordinary light though it was a shiney blue light; the closer they got to it the brighter and deeper the shade of blue became. They turned round a small corner and saw a huge pool of pure blue water just sitting there.

"Maybe that's our way out?" Aubrey says seeing that she might be able to swim out.

"I'm gonna go see how far it is see if we can make it back to land if we swim." She takes off her sneakers and dives right into the pool and swims away under a small rock wall.

It was five minutes before she returned back to the pool, Stacie hadn't stopped worrying that she had gotten lost or couldn't find her way back; so much so that Beca had stopped listening and paying attention to her.

"Thank goodness your back." Stacie says the second she spots the water bubble up with Aubrey inside it.

"Okay I think if we swim the way I just went and go a bit further we can make it, it's not that far and the waters isn't too deep around here so we should be okay to keep going until we reach the land." She says as her head pops up from the water.

Beca does exactly the same as Aubrey did and takes her shoes off getting into the water and staying next to her waiting for Stacie.

"Come in Stace." Beca says wanting to hurry up and go.

"Nope no way I'm not getting in there." She protests against them not happy at all about this.

"It's the only way out Stacie." Aubrey says being the one that explored not finding any other option for them.

She reluctantly climbs in holding onto Beca's hand as she gets in making a slight squeal noise as the water touches her.

The three of them all stand together in the water and a weird flicker happens around them in the water; an incredible yellow light just moving round the three of them. They look up and see through the top of the cave that the moon is hovering over them. The lights continue until the moon passes.

All three girls are confused unsure what had just happened to them. Aubrey is the first to swim off followed by Beca who helps Stacie swim out. They continue to swim until they reach the beach again and are back on dry land.

"What was that?" Stacie ask being the first to bring up the lights from around them.

"I have no idea but this stays between us got it?" Aubrey says making sure nobody else will find out what had happened.

"Right I agree that was too wired." Beca chimes in agreeing completely with Aubrey.

They all walk back to where the boat they came in was.

"Wait how did you get here Beca?" Stacie asks not knowing what way she came to the island.

"My boat is like round the other side" she said assuring Stacie how she came to the island.

"Oh right, well then we'll see you at school tomorrow." She says getting into the boat waiting for Aubrey to get in and start the engine.

"Yeah sure, see you guys tomorrow." Beca walks off to find her own boat leaving the two of them alone.

"Why did you even invite her?" Aubrey says watching Beca walking away as she gets into the boat herself.

"I didn't we just kinda stayed together when we met up after you ditched me." Stacie says replaying how Aubrey had left her.

"Oh right I forget that." She started the engine and started driving off back home leaving the small island that they were on.

Stacie wakes up in a daze she sleepily gets up, grabbing a towel, her clothes and then walks into the bath room. She starts running water ready to relax in the bath. The second the bath is ready she gets in laying in it; within a few seconds she changes sitting there confused looking down where her feet should have been.

Aubrey wakes up ready for the day to begin; she goes into her garden where the family pool was located and dives right into the centre of it ready for her usual morning swim before she goes to school. Almost automatically as she is in the water she starts to feel different the way she was swimming wasn't right. It wasn't until she looked into the water that she saw it, saw what had happened to her.

Beca walks into her community gym after having her usual morning run, feeling really hot and sweaty after running longer and further than she normally does. She walks into the shower stalls checking no one was already in them. She turns the water on waiting until it had ran long enough for it to be warm enough; she steps under with a smile on her face ready to cool down, before she knows it her feet topple her over and she's laying on the ground staring down with confusion and a frown on her face. "What the hell".

"Stacie your phones ringing and can you like hurry up I have school today too you know." Her younger sister yells standing outside the bathroom door.

"Just wait a few minutes Ellie I've not done yet" she says back; looking down again and not having a clue what had happened to her or why.

She switches the switch so the water can start to drain out of the bath, then reaches over for her towel and starts drying herself off. A few minutes later she had dried off completely and her feet came back. She dresses herself fast and runs out the bathroom almost knocking her sister with the door.

She grabs her phone from her bedroom where she had left it and starts calling Aubrey.

Aubrey swims to the end of the pool to her towel and bag she had left there and reaches inside for her phone, seeing that it was Stacie calling her.

"Did it happen to you aswell?" Aubrey says answering the call.

"Yeah it did, get yourself dry and meet me before class we all need to talk." She says and then hangs up her phone.

As the two of them arrive at the school they spot Beca walking and grab her by her arm and pull her to the side so they can all talk privately.

"What the hell" she says as she is being pulled to the side.

"We need to talk urgently" Stacie says sitting down a small wall near where they were.

"Did you get a…a" she stops not knowing the words to say.

"A tail; Stacie and I both got tails the second water touched us. So did you?" Aubrey finishes what Stacie was trying to say.

"Yeah I did, but how did it happen?" She says confusion ridden all over her face.

"Maybe it was the water last night, it was so weird and creepy in that cave." Stacie says thinking back to the weird lights they had seen the night before.

"It could be that but what does that mean about us?" Aubrey says wondering what the tail was all about.

"I think it means we're mermaids"
