After years of schooling on the East Coast, Constance Browning returns to Oregon and the reservation where she grew up with her missionary parents. She is accompanied by Thomas Lowell, her best friend and colleague, and together they embark on a project to catalogue the native peoples of Oregon for the Bureau of American Ethnology. But Connie and Tom have another purpose—to prove her parents are not involved in a secret conspiracy to goad the oppressed tribes into a doomed war.

Connie finds life on the reservation much bleaker than she remembered, and she is glad to have Tom by her side. But she also becomes reacquainted with Clint Singleton, the government agent on whom she had a crush as a girl. Now that she's back, Clint finally seems interested in her, but Connie is no longer sure of her feelings. As tensions on the reservation rise and war looms ever closer, Connie and Tom search for whoever is truly behind the uprising. With danger unfolding amid shocking revelations, Connie will also have a revelation of the heart.
