In Chapter 16, Hannah warns Kit that, without love, she will discover that marrying William will prove a fruitless escape from her uncle's house. Hannah is implying that Kit will not have improved upon her current situation if she acts unwisely; she must marry for love if she wishes to ensure her happiness.
We can tell that love is found in great abundance in Hannah's cottage. Even though Hannah is ostracized because she is a Quaker and thought to be a witch, she welcomes Kit warmly into her life. Her cottage is a place where peace and harmony reign. Kit thinks that even the 'fire in Hannah's hearth seems to have a special glow.'
Hannah's cottage is the place where both Kit and Prudence find love, affection, and acceptance. Prudence, whose mother is the judgmental and bad-tempered Goodwife Cruff, learns how to read and write from Hannah and Kit. In the privacy of Hannah's cabin, Prudence blossoms into a confident and happy child.
For Prudence was an entirely different child from the woebegone shrinking creature who had stood in the roadway outside the school. The tight little bud that was the real Prudence had steadily opened its petals in the sunshine of Kit's friendship and Hannah's gentle affection.
Kit also finds solace in Hannah's home. When she is fired from the schoolhouse for having her young charges act out a skit from a biblical parable, Kit seeks comfort at Hannah's cottage. Because of Hannah's warmth and compassion, both Kit and Prudence find comfort and consolation in her company.
