In Tulsa, Oklahoma, where the divide between Socs and Greasers defines nearly everything, Sienna Randle exists in the space between categories that were never meant to overlap. She is Steve Randle’s younger sister, raised in the same rough edges and crowded chaos of Greaser life, but she never fully becomes part of it in the way people expect. At the same time, she is not a Soc — not truly, not socially, not in the way that group defines itself. Instead, she becomes something far more complicated: a girl who moves between both worlds without belonging completely to either.
