Silence is Golden(Jelsa)

Elsa Black, the one word that people say when they hear her name is scary. She is terrified at her school, not because of how she acts, but because she is silent and her two brothers. She does not speak at all, even in classes, and her brothers have sent the strongest kids into comas. Everyone knows not to mess with Elsa, everyone.

No one knows why Elsa is like this, not even her old best friend Jack Frost. All they know is one day she was smiling and talking, next day she wouldn't say a word. To Jack, Elsa is his biggest mystery, and he is determined to solve her.

Is every case best solved though?
