Two people determined to give their hearts to God alone find love on their journey west to serve as missionaries in 1830's America. Priscilla White knows she'll never be a wife or mother and feels God's call to the mission field in India. Dr. Eli Ernest is back from Oregon Country only long enough to raise awareness of missions to the natives before heading out West once more. But then Priscilla and Eli both receive news from the mission board: No longer will they send unmarried men and women into the field. Left scrambling for options, the two realize the other might be the answer to their needs. Priscilla and Eli agree to a partnership, a marriage in name only that will allow them to follow God's leading into the mission field. But as they journey west, this decision will be tested by the hardships of the trip and by the unexpected turnings of their hearts.
