When Savannah Mast's fiancé dumps her a week before their wedding, she flees California for the safety of her Amish grandmother's farm near Nappanee, Indiana. She's not planning on staying long but becomes unexpectedly entangled in the search for a missing Amish girl. She can't leave—especially not when her childhood friend Tommy Yoder is implicated as a suspect. When Savannah accompanies her grandmother to Plain Patterns, a nearby quilt shop, the owner and local historian, Jane Berger, relates a tale about another woman's disappearance back in the 1800s that has curious echoes to today. Inspired by the story, Savannah does all she can to find the Amish girl and clear Tommy's name. But when her former fiancé shows up, begging her to return to California and marry him after all, she must choose between accepting the security of what he has to offer or continuing the complicated legacy of her family's faith.
