Book excerpt: Points out how British novelist Pym (1913-80) parodied the conventions of romance novels by deflating characters, hyperbole, and exaggeration, or emphasizing meticulously the mundane elements of everyday life. Shows how she used food, clothes, heroin and hero characterizations, and marriage customs to portray her characters,' and perhaps her own, skepticism about the whole business.
