Stewart gives us three sisters whose bond — scratchy and well-worn but stronger for it, as can happen with family ties — is unspoken but effortless.

The fifth installment of Amy Stewart’s clever and original Kopp Sisters series.

In Kopp Sisters on the March, the sisters learn some military discipline—whether they’re ready or not—as the U.S. prepares to enter World War I.

It’s the spring of 1917 and change is in the air. American women have done something remarkable: they’ve banded together to create military-style training camps for women who want to serve. These so-called National Service Schools prove irresistible to the Kopp sisters, who leave their farm in New Jersey to join up.

When an accident befalls the matron, Constance reluctantly agrees to oversee the camp—much to the alarm of the Kopps’ tent-mate, the real-life Beulah Binford, who is seeking refuge from her own scandalous past under the cover of a false identity. Will she be denied a second chance? And after notoriety, can a woman’s life ever be her own again?

In Kopp Sisters on the March, the women of Camp Chevy Chase face down the skepticism of the War Department, the double standards of a scornful public, and the very real perils of war. Once again, Amy Stewart has brilliantly brought a little-known moment in history to light with her fearless and funny Kopp sisters novels.

Reviews & Bookseller Love for Kopp Sisters on the March

"Told in Stewart’s nimble, witty prose, this fifth in the popular series is based largely on fact and offers a paean to patriotism and the role women have played in war, even a century ago. Devoted fans will be pleased with the tantalizing hint Stewart provides about what lies ahead for Constance."
"A feisty, fact-based series...After losing her dream job as Bergen County deputy sheriff, Constance Kopp regroups at a Maryland Army camp for women on the eve of World War I...Plenty of loose ends are dangled for future volumes as Constance and Beulah both make peace with their pasts and plans to move forward."
— Kirkus Reviews
"Set in the spring of 1917, Stewart’s enjoyable fifth Kopp Sisters novel (after 2018’s Miss Kopp Just Won’t Quit) finds the three Kopp sisters ready to do their bit as the U.S. prepares to enter WWI...Convincing characters behave in ways true to their era. Stewart does a wonderful job of illuminating a fascinating period in American history."
"A thrilling mix of history and feminism, this new “Kopp” story contains the same captivating storytelling as the first one, with plenty of nuggets for series fans."
