Prologue

Anastasia's foot tapped lightly to the beat of the music playing through her muggle music listeners. Her head was bobbing as she waited for her friends down at Hogsmeade station. A few Hogwarts students were lazily hanging about, some of them were already rid of their school robes. Anastasia on the other hand was still fully dressed in her Gryffindor uniform. Her friends had sent her down to grab them a compartment in the fourth carriage. Anastasia rolled her eyes at that, her brother was hopelessly too superstitious. She sighed impatiently as more students travelled down in their usual cliques. She stood on her tip toes to see if she could spot either her brother or a head of red, but to no avail.

Sighing again she dropped down onto her feet and softly began to hum the tune of the song. She liked the rhythmic pounding of the drums and the singer's slightly scratchy voice, the noise seemed to sooth her in a way. Anastasia barely heard the last bell ring, signalling the end of the school year. She sighed in relief, no homework for two months sounded like perfection. Anastasia could feel her patience wearing thin when almost the entire school flooded onto the train's deck. She craned her neck in search of her friends; the only thing she spotted was a sea of witches and wizards. Anastasia scowled and stuck her pinkie and thumb into the respective corners of her mouth before she whistled a shrill tune, some of the first years close to her cringed.

Ever since they were little kids, Anastasia and her brother had always had a… unique way of communicating. They had devised a whistling language. At first the tunes were simple words such as, "where", "help", "yes" and "no". Over the years the words developed into sentences and today the two siblings could have an entire conversation without anyone knowing what they were blabbing on about.

"Where are you?" The whistle echoed over the heads of Hogwarts students and Anastasia waited with patience for a reply. She didn't wait long before a faint tune rung from the carriages, "On our way. You can meet us inside." Anastasia huffed as she adjusted her robes and made to walk into the train when someone sharply plucked on her ponytail. Anastasia yelped and tears pricked the corners of her eyes. She turned and wasn't surprised to find James Potter snickering with his group of friends. Anastasia glared as her hand came up to rub at her sensitive scalp, "When are you going to stop being a boy that seeks attention by plucking on a girl's pigtails?"

Potter grinned, a lopsided grin. His brown eyes twinkled in amusement, Anastasia grew only more annoyed. "You know you're the only girl whose attention I want." He said innocently as he wiggled his eyebrows. Anastasia sent him a murderous look. James had been a pain in her butt since her first year when she befriended his brother Albus, the guy was unrelenting and has teased, bullied and gossiped about her ever since. Anastasia personally believed the bastard was born just to tick her off. She snarled and took a deep breath to control her anger before she turned around, determined not to get into a fight with James on the last day of school.

James frowned at her backside: He hadn't had his fun yet, smirking he reached out and ripped her muggle technology from her neck. He hadn't anticipated the cord tangling around her neck or the devise falling to the ground and shattering into two. Anastasia cried out at the rough tug and lost her balance. Before she knew it she was on the ground on her back, the wind knocked out of her. Anastasia gasped for breath along with several other students who saw what happened. The witch lay on the ground her eyes narrowed into slits, while James and his friends laughed at her predicament.

Furiously Anastasia got to her feet and whipped out her wand. The laughter stopped and James nervously chuckled as he eyed her magical weapon. Anastasia's gaze jumped to her broken headphones on the ground. She felt rage consume her faster than ever before.

Most of the population of Howarts surrounded the group of students, eyes wide in anticipation. They were used to James and Anastasia's fights by now, most of the seventh and sixth years merely rolled their eyes and got onto the train, but the others who paid close attention to the usual banters knew immediately why James looked so worried. The pair fought every day at least once, they yell and they insult each other, Demetri had once even stood up for his sister against his best friend's older brother, Anastasia had even broken the elder Potter's nose, but never, never had a wand been drawn.

Half the school knew about Anastasia, not just because of her fights with the infamous Harry Potter's eldest son, but because she was a brilliant witch. She was like a young Hermoine Granger, but not as bookish as the legendary Gryffidor. Anastasia ranked third in her year, behind Rose Weasley and Scorpius Malfoy. That didn't matter though, since Anastasia was the best ranking witch/wizard in school when it came to DADA. And James knew this very well.

"Those were my favourite pair." She snarled. James chuckled again, "Calm down, Boyle, it was an accident." He said as he held up his hands. Anastasia's fired burned even more, "You're a real snake. I'm tired of you picking on me and I've had it with your awful jokes. It ends here and I swear to Merlin that if you ever lay a hand on me again I will jinx you into shreds." She hissed as her wand's tip lightly touched his chest. James snorted and opened his mouth, but before a shred of a whisper could escape his lips, Anastasia yelled,

"Stupify!"

James was thrown back into a tree trunk with a yelp. Anastasia raised her wand again to do more damage when a hand lightly gripped her wrist, "C'mon sis, he's not worth it." Anastasia's eyes cut to her brother. He looked disappointed to the untrained eye, but anyone who really knew Demetri could tell that he was proud by the crinkle of his eyes.

"And I would appreciate it if I don't have to explain to my parents why my brother came home in a body bag." Albus quipped from beside her brother. Anastasia nodded her head and tucked her wand back into her robes. Very well, Potter will live, but if he got near her again, she would roast him alive.
