Master quilter Sylvia Compson discovers a stash of letters in the attic of Elm Creek Manor and traces a tale back to 1859. An escaped slave, Joanna, spent a brief period at Elm Creek Farm until she was captured and returned to bondage, leaving her son in the care of the Bergstrom family. If Sylvia is to determine the fate of Joanna and her son, she must rely on one important clue: the meticulous heirloom quilt Joanna stitched and left behind.
