Disclaimer: Kate and Abby are not mine.

Spoilers: It is AU

"So are you going to tell me where we are now?" Abby asked Kate as they got out of the car at the end of a very long dirt road.

"Well you are in a swimsuit on an island," Kate reminded her, "Do you want to take a guess?" As the talked Kate was leading Abby across the parking lot towards a little bridge. As they reached the other side Abby stopped and looked at Kate.

"We bumped across a dirt road for ten minutes to get to a beach?" Abby asked incredulously, "We own a beach." Kate gave her a wicked smile and took off running up the dunes in front of them. Abby chased Kate up the path, but did not catch her until Kate stopped at the top of the dunes.

"To get to that beach," Kate corrected standing aside so Abby could look out over expanse of sand to the sharp steep waterline and see the wave crashing up on shore.

"Wow," Abby whispered, "Are the waves always this big?"

"No," Kate replied, "A lot of times they're bigger."

"Cool," Abby replied still looking in over the sand at the oversized surf.

"Let's go," Kate told her as Monica came up behind them. They had been required to take Monica along so that they would have help if something where to happen to one of them. Monica just saw as it as a good excuse to hang out on the beach and read her book. It was one of those books that she absolutely did not let anyone know she read.

The three girls made their way down the beach and dropped their towels at the edge of the flat part. Kate and Abby both prepared to dart for the surf, but Monica stopped them.

"You just ate," she reminded them, "You can't swim yet."

"Monica," Kate said rolling her eyes, "If you want to make a sandcastle just ask."

Monica looked like a child caught with their hand in the cookie jar, but then again essentially she was. Building sandcastles was one of the things that the sisters had done when they were much younger and Monica still loved them. She refrained from making them because it was perceived as so out of character for her, but everybody had their quirks.

"Okay," Monica replied, "I want to build a sandcastle." Kate smiled and shook her head then she turned to Abby.

"You got a problem with that Abby?" Kate questioned her friend, who with a sideways glance at the surf, shook her head.

With that the three girls began their construction project. Monica was in charge of constructing a beautiful castle. Kate and Abby were in charge of building an elaborate system of moats and walls that would protect the castle from any waves that could harm it.

They worked in silence for a quarter of an hour. Each of the girls was in deep contemplation on their appointed task. They were lucky and finished everything they need to before the first wave came. They now had an immense structure of sand in front of them. They stood back and looked at it proudly.

At that particular moment a huge wave came sweeping up the beach and put their defenses to the test for the time. The wave move exactly as Kate and Abby had intended it to. It swept up the channels that were made for it and fell into the moat in front of the castle. The castle itself remained untouched.

"Yay!" Kate and Abby cried together exchanging a high five.

"Alright," Monica told them, "You can go in the water now."

"Great," Abby said excitedly, "Let's go." Abby tried to drag Kate towards the water, but Kate broke free as she broke into a sprint. Abby followed closely behind her friend. They stopped with they got knee deep in the water. With one glance they both agreed and on the count of three they dove into the water.

They surface just as a big wave was approaching. Abby ducked under it to avoid getting caught in it. Kate on the other hand propelled herself up through the wave. As the wave broke, Kate went flying out the back of the wave and was in the air for a few seconds before she crashed back into the water.

"Look," Abby pointed out, "the castle took another wave."

"So that makes two," Kate said thinking, "What if we equated each wave to a hundred years of erosion and see how many years it can survive?"

"Good idea," Abby agreed, "let's get Monica to count too."

"Monica," Kate yelled up the beach. Monica wandered towards the water and allowed Kate to explain her plan. The older girl nodded.

"Wave," she told them coolly as she walked away.

"What?" Abby asked. Kate opened her mouth to reply, but she did not get a chance. A giant wave came crashing on top of them. Most places this would have been cause for concern but at this particular beach it was part of the fun. Many people, including both Kate and Monica in past years, deliberately tried to get pummeled by the waves. It added a sort of excitement to the whole experience.

The two girls played in the surf for a long time before Monica walked back to the edge of the water.

"We have to leave now if we want to make it to dinner," she told them.

Abby and Kate exchanged a look. Neither one of them wanted to leave but they also knew that missing dinner would result in certain death. So resignedly theys body surfed their way back into shore and walked up the beach to their towels.

They looked at the sandcastle as they passed and saw that it was in ruins. There was only one of the backmost towers and the remnants of walls and courtyards left.

"How long were we in there for?" Kate asked her sister.

"About 2300 years."

I liked the end bit. Um…yea please review…Anyway…Please Review.
