Maria Nilson's "From The Flame and the Flower to Fifty Shades of Grey: Sex, Power and Desire in the Romance Novel" has been published in Akademisk Kvarter/Academic Quarter 7 (2013): 119-131.
Reading these books [i.e. the Fifty Shades trilogy] mainly as romance, Nilson focuses on how James uses well known and established romance traits from, for example, the so-called “bodice-ripper” novel and chick lit, in order to create a hybrid. These traits are visible in both how James describes her protagonists and in how the relationship between them is portrayed. Nilson argues that the Fifty Shades trilogy is, rather than a new kind of romance, a compilation of well-established traits.The article is available in full, for free, here.
