The "Fifty Shades" trilogy of erotic romance novels has been a publishing sensation, with over seventy million copies sold worldwide since the first volume appeared in 2011. Clearly, "Fifty Shades" is a cultural phenomenon worth serious scrutiny, and sociologist Eva Illouz provides it in this short, engaging book. Illouz first places the trilogy in the context of best-seller publishing, then delves into the nature of its appeal. She argues that the "Fifty Shades "trilogy is neither mommy porn nor anti-feminist hackwork. Rather, she shows that it affords intense reading pleasure to many women readers because it resonates with the sociological structure of men s and women s relationships today. "Fifty Shades," she argues, is a gothic romance adapted to modern times in which sexuality is a source both of division between men and women and a site to orchestrate their reconciliation. But Illouz also wants to show that BDSM is as much a cultural as a sexual fantasy, for it functions here as a self-help category, a guide to a happier romantic life. In other words, "Fifty Shades" is genre fiction that weaves together a commentary on the deprived condition of love and sexuality, a romantic fantasy, and self-help instructions on how to improve the reader s life."
