Three compelling volumes of poetry from a feminist icon, poet, and author of the groundbreaking novel Mrs. Stevens Hears the Mermaids Singing. A Durable Fire: This collection borrows its title from Sir Walter Raleigh, who wrote, "Love is a durable fire / In the mind ever burning." It is a fitting sentiment for a collection on solitude, wherein the author finds herself full of emotion even in seclusion. A Durable Fire is a transformative work by a masterful poet. A Grain of Mustard Seed: In this beautiful collection, Sarton explores dark and destructive femininity. She writes of "Crude power that forges a balance / Between hate and love," finding an amalgam of dark and light within a single act. These graceful and nuanced poems join timeless ideas and specific moments in history. A Private Mythology: To celebrate her fiftieth birthday, Sarton embarked on a pilgrimage around the world. Traveling through Japan, India, and Greece, she captured her spiritual discoveries in this vivid collection of poetry.
