The premise is this. Piglet is in her early 30s and engaged to the ostensibly perfect Kit. The couple have recently moved into a new-build in Oxford, not far from Kit’s parents. During the week Piglet commutes to London, where she works as an editorial assistant for a cookbook publisher. Life, 90 days from the wedding, presents as an idyll. Things, inevitably, must fall apart. Thirteen days before the wedding, Kit confesses to a betrayal and, on cue, cracks begin to show in Piglet’s scrupulously curated life. There is her shame at the wealth disparity between her family and her fiance’s, as her Derbyshire parents enjoy Viennetta unironically and check prices on menus, while Kit’s subsidise the couple’s mortgage and nuptials. There is the growing gulf between Piglet and her best friend, Margot, whose pregnancy heralds the end of girlish fun. There is the strain to survive the simultaneous pressures of planning a wedding and seeking a promotion. There is Piglet’s difficult relationship to food.
