If The Marriage Plot, by Jeffrey Eugenides, had been written by a woman yet still had the same title and wedding ring on its cover, would it have received a great deal of serious literary attention? Or would this novel (which I loved) have been relegated to “Women’s Fiction,” that close-quartered lower shelf where books emphasizing relationships and the interior lives of women are often relegated? Certainly The Marriage Plot, Eugenides’s first novel since his Pulitzer Prize-winning Middlesex, was poised to receive tremendous literary interest regardless of subject matter, but the presence of a female protagonist, the gracefulness, the sometimes nostalgic tone and the relationship-heavy nature of the book only highlight the fact that many first-rate books by women and about women’s lives never find a way to escape “Women’s Fiction” and make the leap onto the upper shelf where certain books, most of them written by men (and, yes, some women — more about them later), are prominently displayed and admired.
