The Mute Curtis Sister

Fizz Elizabeth Curtis (short for Lizzie) is seven years old. Her parents died after her birth, so she doesn't remember them well. The boys have no idea why she's grown mute to everyone around her, and acting so... Strange.

Plus, a mysterious murderer is walking the streets of Tulsa, and is after little children, such as Fizz.

They tried therapy, but nothing's changed. They tried talking to her, and not a single word. The gang all care about her and love her to bits, but they can't seem to figure out what's wrong with her.

She'll take a piece of paper, and she'll write, and speak sign language, but won't speak. She says she's fine.

But her brothers seem to think otherwise.

That is, until she speaks up to one of them.
