Disclaimer- I don't own Harry Potter or Percy Jackson, except for my OC. J.K. Rowling and Rick Riordan does. I use the Harry Potter movies and the Percy Jackson books. (Imagine that Nico can shadow-travel when he was little, but then he got his memory wiped and has to develop it again from Minos later on. You guys know the story, well if you read the originals.) This story is also found on Wattpad.

3rd POV

In the distance, there was a girl, about six years old, running towards a house. Her dark brown hair, almost nearly to black, waved in the cold air around her.

She is Bianca. She continued running away from home. Cold wet droplets fell from her face, landing on the ground. She didn't bring anything with her, for she had nothing that she could bring.

She grew up without a mother. From her father, she heard that her mother had died from a car accident. After her father found out about the accident, he blamed everything on Bianca as she grows up. She reminded him of his wife, and he detested this. Memories of her mother wash in whenever he sees her. He begins the physical treatment on her.

Bianca was just only six. She didn't understand why her father would do this.

She arrived at the familiar brown door, the door that led to the house that always welcomed her. She knocked the door furiously until it opened up.

"Anca..." She heard the familiar voice call upon her nickname.

She looked up, analyzing the black messy hair of a familiar friend. Nico di Angelo.

She huffed, exhaling the stress within her out."Nico," she cried. She leaned towards him, feeling his arms wrap around her in comfort.

"Come on, Anca. Let's get inside."

She nodded.

Bianca, Nico's older sister, started tending her wound on her arm.

Kind of a coincidence that they both have the same name, right?

"Is it better, Anca?" Bianca asked.

Anca nodded. Nico's mother helped clean the tear on her face.

"Strange..." Nico's mother whispered, wiping Anca's face with a towel."Your face is cold."

"Probably from outside, mamma," Nico suggested.

"Anca, are you hungry? There are still some leftovers from our dinner," Nico's mother informed. Anca shook her head."Okay, I'm going to set up your bed in Bianca's room."

Anca nodded, and Nico's mother got up to leave.

Bianca finished fixing Anca's arm with a roll of bandages."There, that should do it."

Anca smiled, staring at her injuries that she received earlier from her supposedly guardian."T-thank you," she croaked out.

"It's no problem, Anca." Bianca got up."Do you want to take a bath?"

Anca shook her head."I'm fine, thank you..."

Bianca nodded."Okay, I'll see you upstairs." She left, leaving Nico and Anca alone.

"You alright, Anca?" Nico asked, gently picking up her bandaged arm.

Anca sighed, slowly nodding."It j-just hurts..."

He released her arm and opened his arms out for a hug. She crawled into his embrace, both holding each other tightly.

"It'll be okay, Anca. It'll be okay," he soothes."I won't let him ever touch you again. You could always stay with us, Anca..."

She sighed, closing her eyes. She drifted off to sleep.

Anca woke up, sweating from a nightmare in Nico's sister's room. She figured that she fell asleep in Nico's arms, and he moved her here. She looked over and watched the clock tick. It was only four in the morning. She got out from her bed. Her arm stung a little, but that didn't stop her. She was frightened. She had to tell Nico about her nightmare. Like always.

She slowly opened the door that led to the hallways. She looked back at Bianca, who was still sound asleep on her bed. She closed the door and walked through the dark halls.

She found Nico's room and opened it gently, careful to not wake anyone else up. She found Nico sleeping on his bed, one leg stuck out in the open. As she entered, she closed the door. She walked closer until she heard Nico softly snoring.

She smiled. She started producing something cold, something that would have never happened during the summer, something so extraordinary for a human being. A snowball. She created a snowball out of her tiny, little hands. She aimed at Nico's face and threw it.

He immediately jumped out from his bed, almost screaming, from the coldness and wetness of the snowball. She covered his mouth, shushing him with her finger on her smiling lips.

She pushed Nico."Scoot over."

He obeyed, and they laid there, looking up at his ceiling.

"Nightmare?" He guessed.

"Yeah. It was about this lady in a pretty white dress. But...she was turning people into ice. It was horrible," Anca recalled.

"Wanna go shadow-travel? It might cheer you up," Nico suggested.

"Okay," Anca smiled.

Nico looked towards his lamp. He found a shadow near him from the lamp area. He grabbed Anca's hand, and they disappeared from the bed. They landed on a tree branch.

Anca turned to him."You had to choose the trees."

He laughed, scratching his messy bed hair."Sorry."

"We're going to be caught, Nico. What if the bad people come and get us?"

Nico chuckled."Like that'll ever happen. they live far, far away. Besides, it's really early in the morning. Who would wake up at this time?"

She smiled. Anca rested on Nico's shoulder while looking up at the sky. Anca's eyes were drooping.

Suddenly, an idea popped into Nico's head.

"Hey...wanna see what I can do?"

Anca got off of him, staring."What is it?" She smiled."Is it one of your tricks again?"

He nodded, grinning at her. He had his hands aimed at the ground. Something bony popped out of the ground. It was a puppy in skeletal form.

"It's a doggy!" She exclaimed."But...it's very skinny..."

They both looked at each other and laughed. They watched as the skeletal dog ran around in circles, chasing after its skeletal tail.

Suddenly, there was a bright light on both their faces.

"There she is!" She heard a male's voice shout.

Fear was written on Anca's face. She noticed that it was one of her dad's friends."I found your daughter, Will!"

"N-Nico..." She shook Nico's arm."W-we need to go. They're after me!"

He nodded, searching around him."L-let me find a shadow..."

They carefully jumped off of the tree branch, landing on the ground. He held her hand tightly, so she wouldn't be afraid. He tried searching for any light source.

"N-Nico..."Anca begged, tearing up. She gripped his hand tighter.

"I-I can't find any shadows!" He cried.

She spotted her dad with something shiny and familiar from his hand, something he used on her before. Knife. Or was it an ax? She began panicking. He threw the sharp object at them. On her own instinct, she let go of Nico's hand, creating ice shards that flew at her dad and the object. It fell to the ground, making a clambering noise as it touched the road.

With the hits of those ice shards, her father collapsed. From afar, she noticed cold blood spilling out from his body.

"Will! Will!" Her dad's friend exclaimed, rushing towards him.

As the friend reached him, kneeling down by her father's side, she watched the friend shake her dad. She couldn't believe that she did that. Her arms fell at her side.

"Anca..." Nico whispered, calling to her.

Anca stared with widened eyes."I-I killed him, Nico. I-I killed my dad..."

Nico shook his head."No, you didn't. It was self-defense! If you didn't do that, the knife would go kill you," he persuaded.

"B-but I killed him, Nico," she whispered.

Nico grabbed her shoulders. They looked at each other, seeing the tears on each other's faces.

"Listen, you're not a murderer, okay?"

Lies, her mind spoke.

"Then why are you crying?" She whispered.

He hesitated."I'm worried about you."

"GET HER!" Someone roared.

They looked above and saw a mob forming. The skeletal dog growled, barking at the mob.

The mob was afraid, but eventually had the courage to destroy the dog. They grabbed both Nico and Bianca, screaming into their faces.

"Killing your own father! That is unacceptable!" A lady cried.

"You should be put in jail!" Someone shouted.

"No! Hanging!" Someone else yelled.

"NOOO!" A familiar voice loudly exclaimed, stopping everyone's movements.

Everyone turned to the loud voice. It was coming from Nico's sister.

She and Nico's mom pushed through the mob to get to both Nico and Anca."She will not go to jail nor go anywhere else!"

"She killed her own father!" Someone brought up.

"What if your own parents were trying to kill you, huh?! What would you have done?!" She argued.

Everyone was silent for awhile. Nico found Anca's hand and gripped it tight.
The temperature dropped in this summer weather. There was sadness and despair in the air. Everyone felt emotionless. They felt dead, like death taking up someone whom we love away from us.

"W-what's going on?" Someone cried.

Anca turned to Nico, who was leaning onto her. She noticed his pale face and droopy eyes.

"Nico?" She called. His legs gave up, falling forward."Nico!" She exclaimed, luckily catching him.

Everything turned back to normal.

"Let's go to the juvenile court and see what the judge has to say," someone suggested.

Bianca sighed, looking at Anca and Nico."Alright then."

Bianca went over to Nico and checked up on him."He'll wake up sooner. He'll be alright," she assured, staring into Anca's concerned eyes.

They went to the juvenile court.

"Bianca Noelle Mist, you are hereby sent to London to be admitted into an orphanage. Case dismissed!" The judge shouted, banging his gavel.

Everyone in the courtroom began cheering, except for Nico, Bianca, and Nico's mom.

Bianca pulled Anca into a meaningful hug."Anca...I'm so sorry. I'm really sorry," she cried.

Anca hugged back."It's okay, Bianca. It's not your fault."

"Why London...Why so far away?" Nico's mother cried, leaning towards Anca. Nico's mom embraced her too tight, almost choking her."Oh...Anca. Oh...sweet, sweet Anca," Nico's mother sobbed into Anca's hair.

The one who was most heartbroken was Nico. It seemed like the world was falling apart. He blamed himself. This would not have happened if he shadow traveled outside.

Anca ran up to him.

"Nico...I-I'm going to miss you," she confessed.

Nico sadly nodded."M-me too."

"I won't forget your shadow-traveling and the dead animals."

"I won't forget your snowballs and you."

He watched her take off her black bracelet. She placed it on Nico's left wrist.

"This is your bracelet, though," he said.

Anca smiled."I know. I want you to keep it. I want you to remember me. Even if I'm gone, I'll be right here. With you."

"I'll be right back."

He quickly went outside to pick up a pink lily he found on the ground. The laid in his palm. The color of it drained to gray, giving it a dead look.

"Here, keep it."

Anca chuckled, accepting the flower."It's a dead flower, Nico. How am I supposed to keep it?"

"Just keep it, Anca. Memories."

She nodded, chuckling."Okay."

They had their last hug.

"Don't faint again, okay?" He nodded. Anca tucked the dead flower in her hair

Nico and his family watched the people take her away.

As Anca arrived at London, she walked into the restroom to use the toilet at the airport.

After using the toilet, she began washing her hands . She glanced at the mirror and noticed a lady in a white dress.

The lady was from her nightmare.

She instinctively shot out snow/ice at the mirror, but it reflected back, hitting Anca's full body. She became what is known as, frozen.
