chunk: To escape a family who does not share her values, Mary befriends Ann, a local girl who educates her still further. Mary becomes quite attached to Ann who is in the grip of an unrequited love and does not reciprocate Mary's feelings. Ann's family falls into poverty and is on the brink of losing their home, but Mary is able to pay off their debts after her marriage to Charles gives her limited control over her money.
  Ann becomes consumptive and Mary travels with her to Lisbon in hopes of nursing her back to health. There they are introduced to Henry, who is also trying to regain his health. Ann dies and Mary is grief-stricken. Henry and Mary subsequently fall in love but are forced to return to England separately. Mary, depressed by her marriage to Charles and bereft of both Ann and Henry, remains unsettled, until she hears that Henry's consumption has worsened. She rushes to his side and cares for him until he dies.
