Little Women was an immediate commercial and critical success, and readers demanded to know more about the characters. Alcott quickly completed a second volume, entitled Good Wives. It was also successful. The two volumes were issued in 1880 in a single work entitled Little Women. Alcott also wrote two sequels to her popular work, both of which also featured the March sisters: Little Men (1871) and Jo's Boys (1886). Although Little Women was a novel for girls, it differed notably from the current writings for children, especially girls. The novel addressed three major themes: "domesticity, work, and true love, all of them interdependent and each necessary to the achievement of its heroine's individual identity." Little Women "has been read as a romance or as a quest, or both. It has been read as a family drama that validates virtue over wealth", but also "as a means of escaping that life by women who knew its gender constraints only too well". According to Sarah Elbert, Alcott created a new form of literature, one that took elements from Romantic children's fiction and combined it with others from sentimental novels, resulting in a totally new format. Elbert argued that within Little Women can be found the first vision of the "All-American girl" and that her multiple aspects are embodied in the differing March sisters.
