Jewett published some 20 books, including Deephaven (1877) and A White Heron and Other Stories (1886), and lived to be just under 60 years old. Despite her age, however, she claimed to have never grown up. "I'm not a bit grown up," she once wrote to Horace Scudder, "and I like my children's books just as well as I ever did." At age 48, she wrote to Annie Adams Fields (widow of publisher James T. Fields), "This is my birthday and I am always nine years old."
Annie Fields lived with Jewett after her husband's death in 1881. The two women shared their homes in what was regularly termed a "Boston marriage" until Jewett's death in 1909. As their friendship blossomed, Jewett's writing began to focus more on matriarchal or female-centric communities. Scholars continue to speculate on their relationship but, according to Jewett biographer Paula Blanchad, "Sarah Orne Jewett fell in love many times, both before and after she met her dearest friend, Annie Fields." Though some contend their friendship was purely platonic, by the 1890s they were treated as a couple by correspondents (one used the term "woman-couple") and split time between the Jewett home in Maine and the Fields home in Boston.
Jewett's writing career ended on her 53rd birthday in 1902. That day, she fell from a carriage and suffered permanent injuries to her head and spine. After her death in 1909, Fields edited a collection of her letters for publication. She introduced the book with a few verses from Edmund Spenser:
For Lovers' eyes more sharply-sighted be
Than other men's, and in dear Love's delight
See more than any other eyes can see.
