Kathryn has written multiple young adult collective biographies on women and war for Chicago Review Press. Her first book, Women Heroes of World War II, gets all the attention, but Booklist gave Kathryn's book on the Pacific Theater of WWII a starred review and likened each chapter to "a cliff-hanger screenplay." And Courageous Women of the Vietnam War was honored with one of those awards that to unfocused eyes sort of resembles the Newbery Medal.

Her first novel, The Belgian Girls, was born of Kathryn's admiration for the European resisters of both world wars, especially Gabrielle Petit, a young Belgian woman who worked for British Intelligence during the First World War.

Kathryn has been seen on WGN TV, "America: Fact vs. Fiction," and the Acorn TV series, "Deception: WWII"; heard on the BBC World Service's "History Hour" program and BBC America; published in The Historian and War, Literature & the Arts; and featured as a guest speaker at the Harold Washington Library in Chicago, the First Division Museum at Cantigny Park, and the Atlanta History Center.
