Eugenides’ third novel and his first after the Pulitzer Prize-winning “Middlesex,” “The Marriage Plot” follows the lives of three college seniors at Brown in the 1980s as their lives form a sort of literary love triangle like that of the 19th-century love stories the narrator studies. Writes Monitor critic Yvonne Zipp, “[S]peaking as a lover of 19th-century novels, it's impossible not to be charmed by Eugenides's defense” of the genre.
