Ronnie lives in a world where you're on one side of the fence, on the inside or the outside. Everyone starts on the inside and aspires to stay there after their testing, where you're meant to find someone with the same tattoo as you; one that everyone's born with. This person is set to be your soul mate. There's only one problem with this theory, Ronnie finds someone with the same tattoo as her, the man who's meant to be her soul mate; before she makes it through the process. And inside the fence that poses as a threat; one Ronnie never thought she would be.
