This story was written for fun and none of the characters other then Sonny and her family belong to me.
Prologue
Hogwarts Express 1971
Sonia Cromwell-Black, affectionately called Sonny, had only been on the Hogwarts Express for 15 minutes before she decided she hated it. Well actually she hated her good for nothing cousins Sirius Black and James Potter for ignoring her struggles to load her trunk on to the overhead rack in favor of discussing pranks and jokes. She was also terrified that James and Sirius seemed to have found each other so fast. Sirius was her first cousin and James being a distant third they had never actually met in person before today. Sonny the Bastard Black as she was often called by Sirius' mother was only even allowed near Sirius' branch of the family because her father's perfect example of blood purity wife was unable to sire him a child meaning Sonny would be the only one he would ever have.
Sonny's mother Nora Cromwell was as pure-blood as they come but the Cromwell family's views on muggles, muggleborns and blood purity failed to align with the Black family's views. So the mad affair between the Ravenclaw and the Slytherin stopped with the threat of cutting off Phineas finically. Yet not before Nora became pregnant. Nora was now a healer at St. Mungo's in fact it is where she met Dorea Potter. Both women had been pregnant at the same time Nora was young and scared and Dorea had been older and never expected to have a child so late in life. The two bonded before realizing that Nora was related to Charlus, however distantly. Sonny and James were more like brother and sister. James being her protector and her saving him from himself.
So Sonny continued to struggle with the massive trunk while the two trouble makers yammered on. Finally fed up the young witch huffed her long black hair out of her face and wandlessly lifted the trunk on to the rack. It was only then that Sirius interjected, "Sonny are you sure that you should have done that?" Just as James asked, "How are you gonna explain that?" Leave it to James and Sirius to only care about rules when it didn't apply to their behavior. Rolling her eyes she replied, "If anyone asks it was accidental magic brought on by my frustration with the trunk and the lack of help I got from my cousins." Now settled into her seat she jokingly asked, "Scared I'll get detention before you two?" For while she would admonish them Sonny was often a willing participant in the trouble the boys respectively got into.
Before either could answer the doors opened to reveal a girl with long red hair and bright green eyes followed closely behind by a boy with greasy black hair and a nose that had obliviously been broken several times and never set properly. The girl softly asked if the compartment was full. With a wave of her hand and a nod Sonny signaled for the duo to join them. Sonny and the girl named Lily quietly conversed about Hogwarts and houses while the hook-nosed boy pulled out an advanced potions book to read. Sonny explained about the difference of the houses and her family's history of being in Ravenclaw but her hope to be in Gryffindor. She told Lily that she could see her as a Ravenclaw. It was this statement that had the hook-nosed boy expounding on the greatness of Slytherin house. Sonny panicked knowing both James' and Sirius' feelings about Slytherin. She quickly interjected that Lily was certainly cunning enough but as a muggleborn she would face a great deal of adversity in that house which was known for its views on blood purity. Sadly the damage of Severus', for that was the boy's name, statements had already been done. Sirius started ranting about all that was wrong with Slytherin and James pulled his wand on the boy to jinx but the train jostled to a start and he hit Lily. Not knowing that the bubble gum pink hair she sported wasn't permanent she screamed. Putting Severus on the defense as Sonny quickly set Lily's hair back to rights.
Once Lily managed to calm Severus it was decided that the two would leave. Sonny left with the duo to help find another compartment and apologize for her cousins' awful behavior. Quickly they found a compartment with a blond girl named Alice. Where she again apologized to Lily for the hair incident and told Severus that while she didn't agree with his opinions he should never be attacked for them even it was just with pink hair. She swiftly exited after that shaking her head having a feeling that she was going to spend the next seven years apologizing for Sirius and James. When she reentered her compartment she was so busy yelling at the two boys that she didn't even realize that another one had joined them. She turned towards the amber-eyed boy who was staring at her in shock and introduced herself, "Hello, I am Sonia Cromwell, most people call me Sonny and I swear I am not part banshee." He chuckled softly and shyly introduced himself, "I am Remus Lupin and I don't think I have ever met someone with purple eyes before."
Oh he was looking at her eyes. Most people didn't have violet eyes. In her family it was a genetic marker of extreme magical power; Power that only her family, James and Sirius knew about which was why they questioned her bold use of non-verbal and wandless magic. She lightly told him they were a rare occurrence in her family then turned the topic towards safer waters. As the train ride progressed the three cousins kept up lighthearted chatter hoping to draw the shy boy out of his shell. Sonny hoped that James and Sirius would at least attempt to learn something and that Remus would accept an offer of friendship from the two hooligans she loved so much he seemed like he could do with a little fun and adventure in his life.
