England, 1914. Poppy is fifteen, beautiful and clever, but society has already carved out her destiny. There's no question of her attending more school; it's too expensive and unsuitable for a girl. Instead, Poppy will become a servant to the aristocratic de Vere family . . . and bury her feelings for their youngest son, Freddie. It doesn't matter that Freddie seems to have fallen just as hard for Poppy. He could never marry a girl like her.
But the set path for Poppy's life is irrevocably altered when it becomes clear that the war isn't going to be over soon. The chains of class, wealth, and her gender no longer matter--England needs every able bodied person to serve in battle in some way. Which, for Poppy, means volunteering on the front lines as a Voluntary Aid Detachment nurse. As she experiences what people are capable of--the best of humanity and the very worst--Poppy will find an unexpected freedom and discover how to be truly her own person.
