I am so so sorry about not starting fast enough! I have been going to sleepovers everyday now! Luckily my silly friend is letting me use her computer. Thanks Sunny!

After my last fanfiction, you guys wanted me to write a sequel. I would love to, but I have no idea what to put in it if I do. If you really want me to do it, just give me ideas.

Anyway, drum roll please! What you have all been waiting for, Sisters Grimm/Percy Jackson Crossover!

Chapter 1

Sabrina came downstairs after receiving a prank from Puck, of course. He had put a snake in her pillow. She hadn't woken anyone up, because, thankfully, she was too shocked to scream.

When she went to the table for breakfast, she had stared murderously at Puck. He had smirked, and continued eating. He was pretty surprised though. He had expected a hissy fit.

Today, they had Granny Relda's famous pink burritoes. Puck, as usual, dug in, while Sabrina had just picked at it, trying to make it look like she was eating. She wasn't fooling anybody though.

A few minutes later, the doorbell rang. Granny Relda got up to get it. She opened the door, where a boy with black hair and green eyes was standing.

"Uh…..hello," he said nervously, "may I speak to Sabrina?"

"Of course, are you a friend of hers?" Relda asked curiously. He just nodded his head.

"Sabrina? A friend of yours is here," she said, gesturing to the boy. She looked up, turned to the boy, and gasped. She ran to him and hugged him.

"Percy?" she asked.

"Hey, Sabrina. Long time, no see, huh?" he asked, smiling.

"How's it going, Seaweed Brain?" she asked. He shook his head, muttering something about stupid nicknames.

"You haven't changed at all," he said.

She stuck her tounge out at him. "Neither have you." He stuck his tounge back at her. She laughed, and they hugged each other again. Puck felt a pang of jealousy for some reason. Granny Relda, however was confused.

"Uhh....Sabrina, who is this?" she asked, trying not to be rude.

Sabrina looked at the boy and they shared a look. "He's my friend, Percy Jackson." He sort of waved and mumbled "hi".

Just then, Daphne came downstairs. She looked very tired.

"What's the noise?" she asked, tired. She spotted Percy, and shrieked.

"Percy!" she screamed, and hugged him so hard, he gasped for air.

"Hey, Daphne.......not too hard!" Daphne blushed.

"Sorry, Seaweed Brain," she smirked.

"Aww, come on, I didn't know you went over to the dark side," he grumbled.

"Which reminds me, where's Annabeth?" she said with a mischievious smile. He blushed.

"She and Thalia are in the car getting some things. Sorry guys, but this wasn't a very happy visit. We've come to bring Sabrina to camp. She needs to help us in the war."

Sabrina turned pale. "It's started?"

"Yes, Kronos has already invaded camp. He is planning for Mount Olympus, and we need to stop him. We also need a lot of people. And I do remember you as a good swordfighter, courtesy of me, of course," he said, proud.

Sabrina snickered. "Oh please, I could kick your butt anyday."

Percy smirked. "I'd like to see you try."

Just then, a girl with blond hair and gray eyes came in. Behind her, was a girl with black hair and was carrying a bow of arrows.

"Annabeth! Thalia!" screamed Sabrina and Daphne. They rushed to them and started talking.

"I missed you guys so much!" said Daphne.

"We missed you too," said Thalia, hugging her.

"Ahem," came Granny Relda from the kitchen. She and Puck were in there looking bewildered. "Could you explain what is going on?"

Sabrina looked at Percy, and he nodded.

"Okay, the first thing I should tell you is that Henry Grimm is not my father," she said. Granny and Puck gasped. "Before my mother met him, she met this man on the beach, and I was born. That man was Poseidon, god of the sea. He also happens to be my father."

"You see, all the Greek gods are real. They've been moving with Western Civilization. They marry mortals and have half blood children. I'm one of them. There are these monsters that try to kill us, because of our scent, but mortals like you guys can't see them, because of the Mist. It covers the eyes of mortals, so they don't know about all of this. The Titans are real too. And Kronos, lord of the titans, is planning to overthrow Mount Olympus. They need my help."

Granny said, "Okay, I believe you. Are you a half blood too, Daphne?"

Daphne sighed. "I wish. No, Henry and Veronica Grimm are my parents. We've always known, but Sabrina made me swear not to tell you, to protect you. Sorry."

"That's okay. But who are you three?" she asked Percy, Annabeth, and Thalia.

Annabeth spoke up. "My name is Annabeth Chase, daughter of Athena. This is Thalia, daughter of Zeus. She's a hunter of Artemis. This is Percy Jackson, son of Poseidon."

Percy smiled, and ruffled Sabrina's hair. "Yup, I'm Sabrina's half-brother." She smacked his hand, and he laughed.

"He happens to be my annoying half-brother. His head is full of kelp. Isn't that right, Seaweed Brain?" Sabrina said. He glared at her, and she laughed.

"My friend, Angela is also my half-sister." (my last fan-fiction! this is before they came back though!)

"Oh yeah, Sabrina, I think you can come out of disguise now," said Annabeth.

"Oh, right!" said Sabrina, and ran out of the room. She came back a few seconds later with the potion in her hand.

"As you can see, I don't look like my father right now, like Percy does. I wanted the monsters confused, so I made a potion to change my skin, hair, and eye color. Nectar, please," she said, gesturing to Percy. He got some kind of drink, and put it in the potion. Sabrina took a sip of it, and her body changed. Her blond hair turned to a black/brown. Her blue eyes turned into sea green. Her pale skin turned into a dark tan.

"Finally, ugh, I hate being a blonde. No offense Annabeth," she said to her, "you are definetely not dumb."

Annabeth blushed, and Percy, Thalia, and Daphne nodded their heads in agreement, and Annabeth turned scarlet.

"So, you see, I have to leave, Daphne can go too. We have to help them defeat Kronos," said Sabrina.

Granny Relda said, "Wait, Sabrina, we have to go with you. Puck, your uncle and I, can't sit here while you're fighting in a war."

Sabrina started to protest, but was cut with a loud roar. Outside was a huge lion.

Thalia gasped. "The Nemean Lion."

Like it? I know what will happen in most of the next chapter, but I really want ideas! And I have to have ideas to write. REVIEW!
