Prologue:
The spirit was high in the Zeller household. Cedonia Zeller's four year old daughter, Rose, had made her mother's wand fly off the counter and into the child's open hand. Cedonia was very proud,
"Oh!" she exclaimed with delight "My little girl is a witch!"
Cedonia had been worried that Rose wouldn't show signs of magical blood. Her husband, Wilford was a muggle and her eldest daughter, Emily, a squib. It also didn't help that Rose's six year old brother, Jarred, hadn't shown signs of magic since he was two.
"I don't get how such a talented boy shows such a lack of magic", the villagers would say whenever Jarred passed by on the way to the market to pick up some potion ingredients with his mum. Even though they were trying to be sentimental, it still made Jarred blush and drop whatever he was holding. This could be very unfortunate, especially when he was holding frogspawn. While Jarred lacked in it, Rose had a knack for magic. She could make herself disappear when she was sad, she could make things fly at her parents when they made her angry, she could make her brother's stuff turn into sand when he drank the last of the pumpkin juice.
Year after year Rose's power strengthened, and her brother's power decreased. Jarred's skin paled and his body slowed. Meanwhile, Rose's face became flushed and her eyes shone energy. Cedonia and Wilford tried as they might to cheer him up. Cedonia comforted him with treats of all sizes whenever he showed any sign of magic at all, and told him stories of how hard it was to perform magic under stress, and that he just needed time and rest. Wilford took a different approach preaching that he was proud of his daughter and would be proud to take on another squib. Jared didn't seem to improve from his parent's words of wisdom, but that didn't stop them from trying. They made sure to separate the two youngest of their children. Nevertheless, Rose still found a way to innocently torture her older brother. Placing fake wands all over the house, setting chocolate frogs on his mattress. Yet whenever one of these schemes occurred, she was always in the right.
Like for instance, one day (now 9 ½ years old) Jarred was hanging up his newest robe to dry after soaking it in warm soapy water, saw a garden gnome shuffling around the yard. At first he froze, afraid of angering the frightening creature. Of course, once he noticed that his sneakoscope was clutched in its stubby fingers he was motivated to try and stop it. He ended up covered in mud, a nasty scratch on his right knee, and no sneakoscope.
It didn't seem like Rose could wriggle out of that one. The sneakoscope was always kept in a locked box and Rose was the only one but him who knew where the key was (he hadn't meant for her to know, it was a long story; involving their older sister's textbooks; their owl, Sinrose; and half a dozen rusty knuts). Eventually, they reasoned that he must have forgotten to close the box properly. They also gave him a scolding for not de-gnoming the well enough. How, Mr. and Mrs. Zeller said, could sweet little 7 year old Rose have done it when she was busy drawing in her room. Plus, anyone could have magicked it out with a simple charm.
So day after day of trouble went on, and no one was ever blamed. Nothing ever changed. Emily and her friend Olivia studied together. Rose doodled in her room, her parents close by admiring her many talents. And Jarred sulked as invitations to various muggle middle schools came in. You could hear him grumbling about the unfairness of them coming years in advance and that they had no heart, terrorizing because of his weaknesses before he was even 11.
Unfortunately, he couldn't hold off forever. The day he turned 11 and was denied from Hogwarts, the school of witchcraft and wizardry, was nearly there. Little did he know, the day would be more wonderful, yet more terrible, than he could ever imagine...
