Hannah Sokolow, the spirited heroine of the international bestseller, The Midwife, returns to tackle new medical challenges in New York. As head midwife for Bellevue Hospital, Hannah faces opposition from male obstetricians who are protecting their turff. After counseling one troubled immigrant woman, Hannah takes a bold step toward a new frontier: sex therapy. When her husband follows his political heart to help the Russian revolution, Hannah follows hers--into a searing affair with a prominent doctor who is separated from her by faith, class, and marriage, but who is driven with a fierce desire that matches her own.
