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."
“Another excellent addition to the Kopp Sisters series, KOPP SISTERS ON THE MARCH boldly takes our heroines to the battlefront -- both in terms of World War I and the rampant sexism of the War Department. It's no surprise that Constance becomes in charge of Camp Chevy Chase; her blend of grit and hapless grace continue to make her more than just an underdog. Stewart keeps her trademark humor in balance with the horrors of war to make this a fantastic historical novel worth reading.”
"In yet another solid installment in this fascinating and addictive series, Stewart continues to mine the historical record and weave the story of the real life Kopp sisters into a fictional rich tale. This time out Constance is reeling from losing her job as sheriff and decides to join her sisters at a camp for women to prepare for the onset of World War I. As usual the Kopp sisters find themselves right at the center of the action and the result is a great read that will have you eagerly anticipating the next adventures from these larger than life characters.”
“With this fifth novel centered on the Kopp sisters, Amy Stewart has clearly moved this series. It’s 1917, and the sisters are involved in the National Service School that actually operated military camps for women just before the U.S. entered WW I. The foibles of the three sisters elicits laughter. Yet their loyalty, love, perseverance, and sense of a justice beyond the law makes you wish you had sisters and friends like them. Once again, Stewart has opened up the historical archives and discovered astonishing stories and events involving real women whose didn’t see themselves as helpless or useless, even when their country went to war. Readers of Maisie Dobbs will revel in finding another series to love in Stewart's tales of the Kopp sisters.”
“Fans of this series already know that the Kopp sisters – Constance, Norma and Fleurette – are not ones to avoid trouble if there’s anything they can do to make things better. Now it’s the spring of 1917 and war is looming, so they do what any self-respecting citizen would do: leave the farm and head for national service. Another thoroughly enjoyable story involving a real life person in need and the sharp wits of the sisters out to help her get through it all make this fifth offering in the series a must-read for fans, anyone interested in WWI and the civilian response in this country, or anyone who just enjoys a good story. It has the well-researched observations about true history we have come to expect from Amy Stewart, couched in an entertaining tale meant to engage our imaginations and give us something to chew on. Once again: Hooray for the Kopp Sisters!”
“This story is my favorite in the series -- it gives us interesting detail on women's participation in the Great War. Stewart's sense of humor adds so much to these tales. She definitely has fans in our bookstore, and we will easily handsell this newest one.”
“Another winner from Amy Stewart! The Kopp sisters head to a training camp for women who want to serve in the upcoming war that is certain to start at any moment. Constance ends up in charge (naturally!), and a woman running from her past throws a wrench into the works. Fun, feminist and fascinating -- Stewart illuminates another little known corner of history.”
"Constance Kopp takes on the military establishment in “Kopp Sisters on the March,” the fifth in Amy Stewart’s entertaining series about three fiercely feminist sisters who refuse to believe that men are meant to rule the world."
"Loosely inspired by an actual crime fighter...the brisk "Kopp Sisters On the March," with Constance and her sisters — crabby Norma and dreamy Fleurette — enrolling in one of the National Service Schools that prepared women for what World War I would require of them, on the home front or overseas."
"Throughout the book, Stewart weaves in reminders of women’s lives from over a century ago."
"Kopp the historical personage must have been extraordinary but Kopp the fictional creation is magnificent. She’s clear-eyed about the obstacles to living life on her terms,but forges ahead anyway. We could all do with a dash of Constance Kopp in our psyches."
