Sadie is as far from normal as one can be: her mother is abusive, her siblings are both mentally incapable and she doesn't have any friends. She also has one major flaw that sets her aside from her peers: she doesn't talk and has no plans to speak anytime soon. After moving across the state, she meets some people: Riley, Daniel, Elaine, Hannah and most importantly, Monroe. These people have no idea what's holding Sadie back, but they accept her without a complaint. Will she reveal why she has been muted, or will the reveal come too late?
