My rating: 4 of 5 stars
Summary: In the idyllic early summer of 1914, life is good for the de Witt family. Rudolf and Verena are planning the wedding of their daughter, Emmeline, while their eldest son Arthur is studying in Paris and Tom is just back from his first term at Cambridge. Celia, the youngest of the de Witt children, is on the brink of adulthood, and secretly dreams of escaping her carefully mapped out future and exploring the world.
But the onslaught of war changes everything and soon the de Witts find themselves sidelined and in danger of losing everything they hold dear. As Celia struggles to make sense of the changing world around her, she lies about her age to join the war effort and finds herself embroiled in a complex plot that puts her and those she loves in danger.
