It's the summer of 1914 - the last peaceful summer Britain will see for four long years. Tilly Moon has long looked to her elder half-sister, Maddy, as a role model. Maddy's love of music inspired Tilly to follow in her footsteps, becoming an accomplished pianist. If there is one thing she loves more than playing the piano though, it is her twin brother's best friend Dominic. But, in the first tentative steps of romance, what they all feared has come to pass. The country is at war.

Following the Moon family's triumphs and tragedies during the outbreak of the First World War, Margaret Thornton's heartfelt and highly evocative narrative brings those turbulent times to life, perfectly capturing the horror of war and the devastating sorrow it brought, but also the heroism it engendered in ordinary people.
