A/N: Hey everyone! I just finished the Percy Jackson series BTW.

H2o setting: After the last episode. Includes Emma and Ash.

Percy Jackson and the Olyimpians: after 'The Last Olympian.' DOES NOT GO INTO THE HERO SERIES, SORRY!

H2o: Just add Water_ RIKKI'S POV

I was collecting my stuff from my boyfriend, Zane, and I's office at the cafè.

"Bye Zane," I said to my boyfriend as I grabbed my bag. I was going to meet the girls for our traditional 'full-moon' sleepover.

Zane looked up from his laptop. As usual, he was playing a computer game. "You meeting Cleo and Bellow at Cleo's?"

I nodded, and then rolled my eyes. "Your forgetting someone." I laughed.

Zane thought for second, then his brown eyes went wide. "Oh yeah, Emma!" He laughed at himself. "Please don't tell her that I forgot about her."

I laughed, Emma and the rest of her family had came home from their around-the-world trip after graduation and Cleo, Bella, and I had defeated the commit. At first Emma was a little spectacle of Bella, being new in there group, then after a few days Emma warmed up to Bella's happy and kind personality.

I opened the door to office and yelled as I shut the door. "No promises."

XxX

(No one's POV)

"Cleo, are you okay?" Asked Emma. The moon was already up and in full view outside. Mr. Sertori, Sam and Kim where in Paris for the summer, by Kim's demand. Cleo said she wanted to spend her summer at home and catch up with Emma. Mr. Sertori agreed since Cleo was going into college next year in Sydney. For the next 3 months she'd be alone in the house.

Cleo was starring mindlessly at her glass on Sprite. Emma followed her gaze and saw the reflection of the moon in the glass. Emma was hypnotized by the moon. They looked at each other and stood up and headed for the door.

Bella and Rikki where in the kitchen, looking for something to eat. Bella heard the door open and close. Rikki had heard to, they glanced at each other. They went to the front hall, in time to see Emma disappear.

Bella looked at her tough sister-like friend. "Do we follow them? Or should we-"

Rikki cut her off by turning the knob of the front door. "We have to help them. No matter the cost. They're our sisters."

Bella nodded and followed Rikki as they left the house. Both unaware it'd be last time for the rest of the summer.

Review! At least 3-5 till the next chapter. It's already finished, :)
