When Sarah's daughter-in-law, Maggie, inherits several items to sell in her store from her great aunt Myrna, Sarah is thrilled to see several quilts in the mix. She's especially interested in one that she recognizes as a pioneer quilt. Sarah explains to Maggie and the twins that this kind of quilt was used by women on the Oregon Trail to recount stories of moving out West in covered wagons. This is good news for the twins because their final project for history class is to do a family tree and tell a unique story about one of their ancestors. But when they compare the antique quilt to the letters their relatives wrote home, they discover that the pioneers took a different path across the country than the one they recorded in the quilt. So which version is correct? And why would Maggie's ancestors lie about their journey? What were they trying to hide?
