Jewel of Promisebegins in late 1860 with newly married Olivia and Alex Duncan ending their long anticipated honeymoon amid the rumbles of discontent in the pro-slavery southern states. Alex's honeymoon gift to Olivia, a black onyx and gold filigree broach, is destined to symbolize a promise of hope they never dreamed possible.

When Lincoln wins the presidential election, they decide to visit Alex's family in South Carolina. Over the course of the next year, they live through Ft. Sumter, the domino secession of southern states, and the war cries of an enraged South. Measuring their understanding of God and humanity against the senior Duncan's statements, Alex and Olivia sadly leave the South while it is still possible.

The day comes when Alex must leave Olivia to join the Union Army. Shortly afterward, Olivia learns she is pregnant. Then comes the fateful day when Alex's name appears in the local newspaper as missing in action and presumed dead. Unable to accept the news, Olivia begins her search for Alex. Going from one military hospital to another, she eventually devotes herself to nursing as she tries to put her life back together. Yet she continues to hope . . .

From the battles of Vicksburg and Gettysburg to the eventual battle at Appomattox, here is a stunning story of courage and honor.
