Brooklynn was born to a very well known and wealthy family on October 5. Her father, Calixtus, worked in Department of Magical Accidents and Catastrophes, while her mother,Layla, worked in the International Magical Office of Law. They started dating after meeting at a Ministry event. A few years went by and Layla found out that she was pregnant. The couple took it as a sign that they should finally get married, and a few months later, they became Mr. and Mrs. Frost. Another few months passed and Brook's older brother Corbin was born. Three years later, the little princess was born. Just after her second birthday, her mother became pregnant with her little brother, Gregory.
Being the only girl, Brook was treated like a princess and given anything that she wanted. She had the father in the palm of her hand and used it to her advantage. Every thing that she did wrong, was quickly turned onto her brothers, while Brook would get away with no punishment. Her mother, on the other hand, always saw through Brook's angelic exterior and did what she good to try and get Brook to see that the way she handled things was wrong.
When Brook was 11, she went to Hogwarts and was sorted into Slytherin, to no ones surprise. She liked to think that she was better than everyone in her classes because of who her family was. She treated everyone like they were inferior, leaving her with few people that actually like her. Her only friend for a few years was Aiden Anderson. In a way, they were very similar in that they didn't really like anyone else, and no one else like them. She developed a huge crush on him, and she was starting to think that he had one on her. She never got to find out though, since he moved to America and hasn't seen him since. After he left, she was alone and had no one. She worked hard to be nice to people, and treat them as equals. Now, she finally had a few friends, and couldn't be happier.
The summer before her seventh, she met Nolan Cook at Flourish and Blotts. It was the first time since Aiden that she had felt anything close to a crush for anyone. He was just so nice to her and made her feel so happy, no matter what he did. Now at school, she's trying to pursue him more, while still focusing on her NEWTs.
