why is the school medal so important to Adelin?

Adeline had an oppressive home life. School gave her a chance to shine. He father ignored her and Adeline thought that he would be pleased if she did really well at school.

"I was winning the medal every week and wearing it constantly. I knew this displeased by siblings, especially Big Sister and Second Brother, but it was the only way to make Father take notice and be proud of me."
