Author's Note: This is my very first fan fiction so please bear with me through my learning experience. I do not own any of the characters in any of the Percy Jackson books. This writing is rated K+. Thank you for reading guys! Reviews would be appreciated. Well, here it goes.

Nico's POV

Nico watched the Poseidon table with interest. He was watching Percy's new sister talk and laugh with him. Gods, he wanted to meet her. A quick recap of what had happened the night before when this girl showed up.

Begin epic Flashback.

Everyone was eating dinner when Connor Stoll, son of Hermes, came running up to the dining pavilion. Connor had been doing a border patrol when he saw a figure running toward the magical barrier. He had assumed that the figure was a mortal. That was when the much larger figure came into view. As the small figure came closer he realized that it was a girl. The larger figure behind her? The "biggest, gnarliest cyclops ever" as Connor put it. Now, this cyclops wasn't the friendly Tyson cyclops, this was the kind of cyclops that would eat you in a heart beat if he could get his hands on you. Well, the girl was running from this thing but it was slowly gaining on her. The girl was almost to the border when she stumbled and fell over a root. The cyclops loomed over her. She tried to get up. Her leg was bent in a weird way that was definitely not natural. The cyclops reached down to pick her up. She drew a sword, which Connor hadn't even noticed when he thought she was a mortal. She slashed the cyclops's fingers and crawled even closer to the magical border. Then, finally, Connor snapped out of his state of shock. He sprinted over the boundary and scooped her up. When he got her across the border, he laid her down and ran to get help. Chiron, Percy, Annabeth, and Connor went back to the spot where she had been set. She lay motionless, covered in blood. Chiron instructed Percy to put her up on his back and galloped to the Big House to the infirmary. She was set on the table and some Apollo kids rushed busily around her attending to her wounds. Her golden brown hair was matted with blood, her tanned skin was littered with cuts and bruises. Some ambrosia and nectar were forced down her throat and about ten minutes later she woke with a jolt. Percy looked at her and introduced himself, along with Annabeth, Connor, and Chiron.

She paled when she saw Chiron, "Y-you're a horse?"

Chiron corrected her, "Actually, I am a-"

He was cut short. The girl interrupted him, "A centaur. I know."

Everyone in the room looked shocked at the fact that she knew Chiron was a centaur. Usually when a new camper shows up, they freak out when Chiron tells them that he is a centaur. This girl already knew that he was a centaur.

Percy broke the silence, "So, what's your name?"

The girl paused, "My name? My name is Macey."

Percy looked at her. He studied her features. She had golden brown, medium length hair, tan skin, and green eyes. Wait! Green Eyes?! As if on cue, a green swirling trident appeared above the girl's head. She looked up at it.

"Y-you... wha-... sist-?" Percy stammered.

Annabeth pitched in, "What my idiot boyfriend means is that you're his sister." She smiled when she said this.

Macey looked excited, "Poseidon, he's your dad too?"

Percy nodded. "How do you know that Poseidon is your dad?"

She replied, "He is the one who told me how to find this place. And the trident kinda gave it away"

All of the people in the room nodded.

Percy inquired, "How old are you?"

Macey answered, "I'm 14."

Percy got excited. "Sweet! I've got a little sister!"

End flashback.

Nico was snapped out of his flashback when he heard Percy's voice.

"Nico. Nico!"

"Wha-?" Nico came back to reality. He blushed when he saw Macey.

"Dude, I was trying to introduce you to my little sister Macey!" Percy told Nico.
Macey smiled and waved at Nico when Percy said her name.

Nico couldn't help it. He smiled back, and it must have been awkward because Macey laughed at him.
