Every brilliant person comes with problems. Even if that brilliant person is a child.
At least, it seems that way for Nathan. All he wanted was a perfect family. Is that too much to ask?
But instead of a perfect child, he got Cassie. She's a genius, sure, but she's not what he wanted. He doesn't care that she's a virtuoso on the violin or doing college level work at ten. She doesn't speak. Ever. To anyone.
And Nathan knows that that means there's something wrong with her. No matter what his wife says, he has to do something about his daughter.
He'll do anything to keep up the facade of having a perfect family, even if that means getting rid of Cassie. Someone has to stop him, but how will anyone know what's going on if Cassie can't tell them?
Having the perfect family just turned into a matter of life or death.
