HELLO.

This was going to be a one shot, but I extended it. It should just be good fun. Hope you like it!

For the record, This actually includes Heroes of Olympus characters, but I couldn't find that on the list...

Disclaimer: I own non of the characters. They are Rick Riodan's.

Although, I did once throw a cheap Ikea vase at someone's head.

The door rattled. Annabeth woke up from her doze on the couch, groggy and slightly dizzy. There was numbness through her whole body; pins and needles in her feet were she'd been pressing them into the wood of the couch end. The reruns of greatest designs were still on

Her dad wasn't meant to be home for several hours. But it was 10 o'clock. Who would be at the Chase family door at ten o'clock?

Annabeth walked cautiously down the hall toward the front door. She silently picked up a cheap Ikea vase and clicked the lock on the door, swinging it slowly open.

Noone was there.

"Hello?" her voice cracked somewhere in those five letters.

"Hey…"

The person right next to her, whispering in her ear, didn't get a chance to finish. Annabeth screamed and smashed the Ikea vase over his head, hard.

"Jesus!" Percy Jackson swore, "God, Annabeth, that hurt!"

"Oh my god!" Annabeth shrieked, "Oh my god, oh my god…oh my god…don't ever do that again! You scared me half to death!"

"I'm fine, by the way," Percy said dryly.

Annabeth put her hands on her hips, "What are you doing here? What do you want?"

"Hey," Percy smiled, "Can't I say Happy Birthday to my girlfriend without having my motives questioned? Nice PJs, by the way."

"It's ten pm. You can't come inside. My dad would kill you…"

Annabeth could of kept the lecture up for a long time, but she realized Percy wasn't paying attention. Well, to her voice anyway.

"Oi," she ducked down, "My eyes aren't that far down, Seaweed Brain."

He smirked, "I was looking at your necklace."

Annabeth opened her mouth, but Percy suddenly covered her lips with his. And that was the end of any prior argument. Because whenever Percy Jackson kissed her, her forever thinking, whirling brain melted. He became her whole world. She threw her arms around his neck and he pulled her against him- suddenly her back was against the front of her house and her legs were wrapped around his waist.

"Happy Birthday, Annabeth," Percy whispered as her trailed kisses across her cheek.

She had no idea how long they stayed there, but by the time they finished, her hair felt a mess and her lips felt bruised. Percy looked just as flustered, which made Annabeth feel a little smug.

"My dad isn't coming home until the morning," Annabeth breathed.

Percy's eyes sparkled, "Naughty Annabeth."

She wacked his shoulder, "I mean, if you want to come inside for a bit, you may."

He followed her through the door she'd left open, trailing a little behind.

She suddenly remembered, "Is your head okay? Do you need an icepack?"

"Nope. My mum always said I had a head like a rock," he tapped it, grinning.

Kevin McCloud's voice seemed a lot louder now than the volume she'd left the TV. Percy suddenly shot out in front of her and glanced into the living room. His eyes suddenly went wide.

Annabeth walked faster to catch up with him, Percy, watching Grand Designs isn't that weird…"

"Arg!" he shoved in front of her, blocking her view of the room, "Actually, I do need an icepack! Desperately! I think my skull is cracked! If I don't get an icepack right now, I'm going to drop dead right in the middle of your hallway!"
"Jesus Percy, calm down," Annabeth said, startled, "I'll get you an ice pack."

He calmed down, "Sorry."

"That's fine, weirdo," she pecked him on the cheek, "I don't want you dying on my hallway rug. Dad just had it steam cleaned."

She walked to the kitchen and fished an icepack out of the freezer. Her boyfriend was so weird.

Then again, it was her seventeenth birthday and she was home alone watch Grand Design reruns. Maybe they were made for each other.

She wrapped the burning cold pack in a tea towel and carried it down the hall. Percy had disappeared from the doorway, and all the lights were off, making the house eerily dark.

Annabeth felt her lip involuntarily quiver, "Percy?"

Even the TV was off. She knew it was some sort of prank, but it didn't stop her feeling a little vulnerable.

She fumbled and found the light switch, "Not funny anymore, Seaweed Brain…"

Heart attack.

"HAPPY BIRTHDAY ANNABETH!"

The room was littered with balloons. Neatly wrapped presents were piled in the corner. The coffee table was decorated with bowls of food, a giant cake shaped like the Sydney Harbour Bridge, her favourite piece of architecture centring them. A giant banner was pinned up between the curtains, reading 'YOU THOUGHT WE FORGOT, DIDN'T YOU, NERD?'

As her friends jumped out from behind various household objects, Annabeth jumped out of her skin. Piper and Hazel appeared behind the TV. Jason, Reyna and Frank leapt out from behind the couch. Leo and Thalia popped out from the bookcase. Nico, who appeared to have not made an effort at all, waved at her from a kitchen chair absentmindedly.

Annabeth put a hand over her mouth to stop her heart coming out of her mouth, "Guys!"

"Surprise," Percy appeared behind her, draping his arms over her shoulders.

"How…" she tried to find words, "What did you do to my living room?"

"We had plenty of time. And for the record, Percy improvised his distraction," Piper bounced over to her, "You left the door wide open, remember?"

"Distraction?" she turned to face Percy.

"Yes. But that didn't mean I didn't enjoy it…"

She rolled her eyes, "You guys are all so weird."

"Do you like the banner? I made the banner!" Leo called.

Everyone swarmed to wish her Happy Birthday. She hugged everyone, even Nico, who went very stiff in her arms before feebly patting her shoulder back.

The party was fun, even after the freak out at the beginning. They turned up the music, danced, ate her cake and played games. Everyone was enjoying themselves. Annabeth completely forgot about her early wish for a quiet family celebration. She was having a lot more fun than dinner with her dad and stepmother.

She and her friends slowly wore out after a couple of hours. They ended up sitting in an awkward circle on the rug, Leo lying back with a party with a party horn between his teeth, Nico hugging his knees to his chest, Reyna awkwardly seated by Hazel between Piper and Jason, creating an awkward love-line that Reyna didn't look like she wanted to be involved in, Frank and Hazel leaning on each other's backs, and Thalia was lying on her stomach with her bare feet in the air. Annabeth was lying on her back with her head in Percy's lap, who was leaning back on his hands.

"You guys," Annabeth said to the roof, "are the best."

"We know," chimed everyone in never-to-be-repeated unison, before bursting into laughter.

"People," Percy glanced at his watch, "Annabeth's folk aren't coming back until late morning. What do you want to do?"

"Something we'll all regret in the morning," Hazel suggested. When Leo sat up and opened his mouth, she quickly added, "And that's not too illegal."

Leo screwed up his nose and lay back down again.

Piper looked smug, "What a good old fashion game of Extreme Truth or Dare? Emphasis," she added as the boys looked horrified, "On Extreme."

"Why not?" Annabeth shrugged in Percy lap.

Reyna and Nico both looked ten times more uncomfortable.

Leo sat up, "Sounds fun. Question- is anything allowed?"

"Within legal range," Piper told him.

Annabeth sat up, "Oh man. We are going to regret this. Vow. What happens at this party, stays with this party."

Everyone nodded.

"Okay. Lets play, weirdos."
