In 1942, London, Nancy Mitford is worried about more than air raids and German spies. Still recovering from a devastating loss, the once sparkling Bright Young Thing is estranged from her husband, her allowance has been cut, and she’s given up her writing career. On top of this, her five beautiful but infamous sisters continue making headlines with their controversial politics. Eager for distraction and desperate for income, Nancy jumps at the chance to manage the Heywood Hill bookshop while the owner is away at war. Between the shop’s brisk business and the literary salons she hosts for her eccentric friends, Nancy’s life seems on the upswing. But when a mysterious French officer insists that she has a story to tell, Nancy must decide if picking up the pen again and revealing all is worth the price she might be forced to pay.
