Romantic pulp fiction
written by women
Usually about a 30something woman
with "the job" and "the house" but lacking "Mr Right
Plot: woman finds man.
In my own experience, these tend to be read when the brain needs a break from quantum mechanics, the eyes need bigger print, the wallet forces use of the library and schedule demands a book that can be read in a day.
Also known as chick lit and chick fic
There are gems among the trash however, Bridget Jones's Diary by Helen Fielding and anything by Marion Keyes.
