Contemporary romance is a subgenre of romance novels, generally set contemporaneously with the time of its writing. The largest of the romance novel subgenres, contemporary romance novels usually reflect the mores of their time. Heroines in the contemporary romances written prior to 1970 usually quit working when they married or had children, while those novels written after 1970 usually have, and keep, a career. As contemporary romance novels have grown to contain more complex plotting and more realistic characters, the line between this subgenre and the genre of women's fiction has blurred.
