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.

Ainsley is randomly teleported into The Outsiders. When she gets jumped right outside the Curtis house, Darry, Dally, Soda, and Two-Bit rush to the rescue. She can't figure out to get home, and can't reveal that she's knows everything that's gonna happen to them. And when her best friend Mo shows up, the drama is taken to a new level since Dally can't seem to take his eyes (and hands) off of Mo. Will she live amongst the outsiders? Can she find a way home and save Dally and Johnny?
