This story begins in Harry Potter and the Half-Blood Prince.
She was so hungry and couldn't sleep. Being locked in the basement was no fun. It was dark and a little cold, so she clambered under her blankets. A few minutes later, she heard footsteps coming down the stairs, so she pushed the blankets under the bed and sat down, pulling her knees up to her chest, her heart beating fast. Her cousin had brought her the blankets secretly one night, so she needed to keep his secret so he wouldn't get into trouble; although he probably wouldn't get into trouble as everyone in the family sees him as 'The Golden Child'. Not that she minded too much; she wished she liked her family, but she doesn't. They all believe in the most terrible things. She knew her cousin believes them too, but he was her only friend.
The door knob turned and opened slowly. "Hey," he whispered, closing the door behind him, slowly.
"No, get out," she whispered, angrily, to her cousin.
"I brought you food!" he whispered, chucking some pumpkin pasties and sandwiches at her.
"Please go away, I don't want to get in trouble," she moaned, quietly, putting the food in a pile at the foot of her bed.
"Ok ok," he muttered, backing out of the room before closing the door, silently. She felt bad, but it scared her too much, the idea of being punished again. She hid half of the food in the hole in the wall behind the shelves for the next morning before running back to the bed and cramming a sandwich into her mouth. Groaning slightly as the ache of her stomach eased, she lay back against her pillow.
I hope you enjoyed Chapter 1. The chapters should get longer. Please let me know if there are any parts that you disagree with (in this and in future chapters), like if I put a date in in which the event could not have plausibly happened in, according to J. K. Rowling's fabulous works of art.
I haven't yet decided on the name of the girl (if you have any suggestions?), but I wanted to get this first chapter out.
