Three very different young women serve as air ambulance nurses bravely flying into WWII combat zones risking their lives to evacuate the wounded. Irish Maeve joined the RAF after her fiancé was killed; streetwise Etta fled London's slums in search of a better life, and farm girl Betty enlisted to prevent the wounded from dying like her brother.

Newspapers have given these women a romantic nickname: "The Flying Nightingales." Not that there's anything romantic about what they do. The horrific injuries they encounter on a daily basis take their toll, so when one of the Nightingales is found dead, they wonder: Was it an accident? Suicide? Or something else?

After another nursing orderly dies mysteriously, they think: Someone's killing Nightingales. The friends grapple with their loss all while keeping a stiff upper lip and continuing to care for casualties as they're being strafed by the Luftwaffe.

Inspired by true events this novel is a tribute to a group of overlooked heroes who kept calm and carried on, while the fighting raged about them. These courageous women proudly did their bit for King and country and found solace and camaraderie in the lasting friendships forged in war.
