Leaves From the Valley — Joanna Trollope

When Captian Edgar Drummond learns he is to serve his first commission in the Crimea, he decides to take his two sisters with him. It will, after all, be only the smallest of skirmishes and, since childhood he, Blanche and Sarah have been inseparable.

The stiff and talentless Edgar, however, soon finds that his beloved reason and order are ineffectual amidst the chaos of a brutal war. Blanche, too, the beauty of the family, longing for frivolous gaiety and the company of handsome young officers, is soon reduced to frustrated boredom which finally results in her bringing disgrace on all of them.

It is Sarah, brave, loyal, intelligent, who is most affected by the horrors that surround her-Sarah who decides she must play an active part in helping the victims of the war. And it is Sarah who, silently, falls in love with the disturbingly honest man who first exposed her to the realities of the Crimean conflict-Robert Chiltern-who, loved by Sarah, is bewitched by her charming and feckless sister.
