1947: Mary Frances Gerety, a young copywriter in an eminent advertising agency, has to convince the world of two things - that marriage means a diamond ring on every woman's finger, and that she is as good at her job as any man. And then, in one moment of brilliant inspiration, Mary Frances writes down four words which will achieve both her aims. . . Moving from a Harvard swim-meet in 1927 to the three-martini lunches of 1940s advertising, from the back streets of 1980s Boston to an exquisite Parisian music shop in 2003, THE ENGAGEMENTS is a novel about love, marriage, commitment and betrayal; it is as sharp, as fiery and as beautiful as the stone we have taken to represent our dreams.
