With Her in Ourland by Charlotte Perkins Gilman

Sequel to Herland.
Published serially in the author's monthly magazine, Forerunner, volume 7 (1916).

Herland described an all-women utopia in a secluded high valley, where 3 adventurous young men visit by airplane. Eventually, 2 of the 3 are expelled, along with a young Herland woman who has married one of the men. With Her in Ourland continues as the husband and wife tour the world outside of Herland, interviewing people, taking notes and photographs, and discussing history, religions, war, child-rearing, the role of women, treatment of immigrants, women's suffrage, and more. The two novels together convey the author's social criticisms of our world at her time and her prescriptions to improve the human condition in the United States.
