Since Keziah Sirrine’s husband disappeared on a mission trip to the frontier, she’s survived by selling herbal remedies and midwifing. Then the Chief Steward of the Congregation sells her house out from under her to fund the group’s move to the wilderness of Iowa and Keziah is forced to go along.

Duncan Ross becomes a member of the Congregation, hoping for a place to call home, to be part of something bigger than himself. He joins forces with Keziah for the health of the Congregation. As respect grows into love, Keziah wonders if she can trust Duncan with her secret.

In the isolation of Preparation, the Chief Steward declares himself anointed of God, demands members relinquish all possessions, and dodges questions about finances. As tensions boil into violence, news of Keziah’s missing husband has Duncan wondering if their love—and Preparation—will survive.
