My education / Susan Choi.

Enhanced descriptions from Syndetics:

An intimately charged novel of desire and disaster from the author of American Woman and A Person of Interest

Regina Gottlieb had been warned about Professor Nicholas Brodeur long before arriving as a graduate student at his prestigious university high on a pastoral hill.  He's said to lie in the dark in his office while undergraduate women read couplets to him. He's condemned on the walls of the women's restroom, and enjoys films by Roman Polanski. But no one has warned Regina about his exceptional physical beauty--or his charismatic, volatile wife.

My Education is the story of Regina's mistakes, which only begin in the bedroom, and end--if they do--fifteen years in the future and thousands of miles away. By turns erotic and completely catastrophic, Regina's misadventures demonstrate what can happen when the chasm between desire and duty is too wide to bridge.
