Sarah Turner is a widowed Lehigh Canal lock tender who has resolved to find a way off the canal. She has her hands full tending the locks, raising three children, and baking bread and washing clothes for some of the boatmen. Sarah isn't looking for love, and she's vowed never to lose her heart to a boatman. But when she meets easy'going captain Elias Brooks, her determination begins to falter.
Captain Elias Brooks is certain that no woman will ever see anything in him beyond the ugly red birthmark on his face - and until he met Sarah Turner, that never mattered to him. But a handsome locksmith also has his cap set for Sarah. Will Sarah follow her heart where it leads?
