The Rainbow Trail is a sequel to The Riders of the Purple Sage. Both novels are notable for their protagonists' mild opposition to Mormon polygamy, but in The Rainbow Trail this theme is treated more explicitly. The plots of both books revolve around the victimization of women in the Mormon culture: events in Riders of the Purple Sage are centered on the struggle of a Mormon woman who sacrifices her wealth and social status to avoid becoming a junior wife of the head of a local church, while The Rainbow Trail contrasts the older Mormons with the rising generation of Mormon women who will not tolerate polygamy and Mormon men who do not seek it.
