Emma Morley and Dexter Mayhew, casual acquaintances during their university years, spend graduation night together. It’s July 15, 1988, and their futures are up in the air. Dexter, the handsome, confident son of a well-to-do family, knows only that he wants “to be successful. . . . to live life to the extreme, but without any mess or complications” [p. 9]. Emma is determined to stay true to her left-leaning passions and ideals though she has little idea of how she’ll do it. They part the next day with vague promises to keep in touch as Dexter sets off to travel the world and Emma returns to her working-class family in Leeds to figure out what she’ll do next. Over the next twenty years, they’ll think about each other, sometimes to meet and reignite a relationship that neither can give up nor explain. One Day revisits Dexter and Emma every year on the anniversary of their first night together. Each July 15th becomes a snapshot of a particular time and place, offering an irresistible and often hilarious chronicle of the lovers they acquire, the careers they pursue, the culture that influences them, and the opportunities they embrace or squander. As their stories unfold, David Nicholls brilliantly explores the interplay of character and fate that shape our lives.
