Cynthia also co-authored the book, Women in Pants: Manly Maidens, Cowgirls and Other Renegades, published by Harry N. Abrams in 2003.

Inspired by Greig's installation, New Eden: The Life and Work of Isabelle Raymond, which features her creation of a fictional 19th-century cross-dressing photographer, the book chronicles some of the real women—both celebrated and ordinary—who broke from society's expectations not only in the way they dressed, but the way they lived their lives. The editor's synopsis and review excerpts below:

Despite what most people may think, American women have always worn pants. Featuring an unusual collection of vintage photographs from the 1850s to the 1920s, Women in Pants documents an almost forgotten revolution in clothing. Defying convention, Victorian dress reformers as well as farmers, laborers, miners, cowgirls, and sportswomen openly wore trousers, while other women disguised themselves in men's attire to get good jobs, go to combat, engage in relationships with other women, or experiment with gender identity.
Candid, often humorous quotes from contemporary newspapers and magazines complement the photographs and enhance our understanding of the culture and time< in which these women lived. For some, wearing pants was a necessity; for others, it was an act of defiance; for still others, it was just fun.
