She was remarried in 1922 to António Guimarães. Espanca had another miscarriage in 1923 and Guimarães filed for divorce a few months later. "Livro de Soror Saudade" (Sister Saudade's Book) was published the same year. In 1925 she was married for a third time to Mário Lage, a doctor who had treated her for a long time. In the sonnet, "Amar" (Love), which was published in her last book, "Charneca em Flor" (Heath in Bloom), Espanca expressed a "consuming desire to satisfy her need to love freely as a woman and her inability to channel that love into a socially acceptable, exclusive, monogamous mode," which according to Thomas Braga, was a revolutionary statement for Portuguese love sonnets.
