Dear Miss Kopp (Kopp Sisters #6) by Amy Stewart; 2020. Softcover.

The indomitable Kopp sisters are tested at home and abroad in this warm and witty tale of wartime courage and camaraderie.

The U.S. has finally entered World War I is and Constance is chasing down suspected German saboteurs and spies for the Bureau of Investigation while Fleurette is traveling across the country entertaining troops with song and dance. Meanwhile, at an undisclosed location in France, Norma is overseeing her thwarted pigeon project for the Army Signal Corps. When Aggie, a nurse at the American field hospital, is accused of stealing essential medical supplies, the intrepid Norma is on the case to find the true culprit.

The far-flung sisters—separated for the first time in their lives—correspond with news of their days. The world has irrevocably changed—will the sisters be content to return to the New Jersey farm when the war is over?
