She won an O. Henry Award in 1991 for her short story "In Which John Imagines His Mind as a Pond." Andre Dubus III wrote in the Los Angeles Times: "Jersild's language is cool and spare, her details muted, a style that serves her heart-thumping main character well, taking him, and us, to an ending that unfolds itself naturally, with a deliberate and excusable echo of James Joyce's The Dead."^[1] She is the author of Happy Hours: Alcohol in a Woman’s Life (HarperCollins), and has lectured widely on the subject of alcohol, as well as appearing on television shows, including The Oprah Winfrey Show and The Montel Williams Show.^[2]

Jersild and her husband, writer Jay Parini (with whom she has three sons), adapted Parini's historical novel Benjamin's Crossing into a screenplay.^[3]
