Caleb and Annie are two young children who have had no mother for several years. Then one day, Sarah, a lady from Maine, answers an advertisement their father, Jacob, put in a newspaper, giving new hope to the family of three. Will she be the one to fill the emptiness in their hearts and the silence in their home, at last?
Some adjustments will have to be made first. Sarah has to get used to living away from the ocean that she has known and loved all her life. Jacob has to get used to having a headstrong wife who is just as good at carpentry as he is. The children have to get used to a new and unorthodox mother.
