The beginning of the first chapter...

Chapter 1
Carrie Jacobs found herself dashing around the corner of her living room and sprinting up her winding set of stairs with the force of a small tornado, her two younger siblings attempting eagerly to keep pace with the speed demon.
“Come on, Carrie. Give us the key!”
“Yeah, this isn’t funny. Where did you even get handcuffs anyway?” Unlike her sister who was only a few years younger than Carrie, her brother was able to restrain any unwanted feelings of hatred at least until things escalated to a totally unwanted level. Carrie had found herself bored after school and used a pair of handcuffs to tether her younger siblings together. That slightly younger boy that she was only just friends with had all kinds of useless junk lying around his house that he liked to share with her.
Reaching the top of the stairs first, Carrie was able to successfully seclude herself to her room for a whole seven seconds before her door was hit with such repeated force that she was nervous they might actually kick it in. While she felt no fear from her siblings, the wrath enforced by her parents was a whole other story and the penalty for knocking the door off its hinges would lie strictly on her shoulders as the oldest of the children.
“Okay okay, calm down,” replied Carrie. She had to grab Amanda’s hand out of mid-air to prevent her from finishing off the door. Brent had taken a more reserved approach and merely decided to sit down against the wall while his sister gave Carrie’e door a beating as if it were a punching bag. Carrie took the key out of her pocket and reluctantly freed her siblings. Amanda mumbled a stream of incoherent jumble and walked off in defeat, while Brent merely rubbed his sore wrist, seemingly apathetic towards the idea that he was now free. He followed Carrie back into her room and sat down on her bed while Carrie spun the handcuffs around her finger with a smug sense of satisfaction devouring her already impulsive ego.
“Why’d you handcuff us anyway?” Brent didn’t seem bothered, just inquisitive.
“Sorry. It was more to annoy Amanda than it was you. I know that you can take these things and walk away laughing, or at least with a neutral look about you. Amanda isn’t like that and it makes me smile to see her so frustrated.” She had no reason to lie about it. Amanda was always a bit of a nuisance to her. If she wasn’t helping herself to half of Carrie’s belongings then she was complaining to her parents that she should have the same rights and responsibilities as Carrie when she was clearly not ready for such things. Brent was polishing his glasses on his t-shirt and acting a little too compulsive in the process as he struggled with a particularly stubborn smudge.
“I’ve gotten used to it,” he replied while walking out of her room, “just try not to annoy her to the point that she tries to include me on her violent schemes for revenge.”
“Gotcha.”
