"Luke" Hamilton has been living as a husband and father for the past seventeen years. No one but her wife, Nora, knows she is not the man she appears to be. They have raised their daughters to become honest and hard-working young women, but even with their loving foundation, Amy and Nattie are hiding their own secrets.

Just as Luke sets out on a dangerous trip to Fort Boise, a newcomer arrives on the ranch—Rika Aaldenberg, who traveled to Oregon as a mail-order bride, hiding that she's not the woman in the letters.

When hidden truths are revealed, will their lives and their family fall apart or will love keep them together?
