Romance and historical information are combined in this story of a sixteen year old girl working out her indenture in a Massachusetts town dominated by its advanced iron works. The heroine, Joanna Sprague, had fled to the New World with her father when Roundheads had forced them from their manor house. When her father died, on board ship, Joanna, though once wealthy, was left penniless and had to accept bondage in order to pay of her passage. She was chosen as kitchen maid for John Gifford, the Iron Master. Gifford, his wife, mother, daughter, and housekeeper, are a cross, dour group, but after a strict, puritanical initiation, Joanna manages to soothe them all and enliven the household. At the same time she makes several friends, whom she has occasion to rescue dramatically. And she also falls in love with Ross McCrae, one of a group of Scotsmen sold to work at the Ironworks. The details of the small, Puritan, Colonial town are smoothly incorporated into the story, which is adequate to hold the interest of teenaged girls.
