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. Arresting images and meditations on the differences between East and West are rendered in this "colorful, polished" winner of the Emily Clark Balch Prize ( Kirkus Reviews ).
