Cutting for Stone by Abraham Verghese
From Vintage Books:
A sweeping, emotionally riveting novel with over one million copies sold—an enthralling family saga of Africa and America, doctors and patients, exile and home.
Marion and Shiva Stone are twin brothers born of a secret union between a beautiful Indian nun and a brash British surgeon. Orphaned by their mother’s death and their father’s disappearance, bound together by a preternatural connection and a shared fascination with medicine, the twins come of age as Ethiopia hovers on the brink of revolution.
Moving from Addis Ababa to New York City and back again, Cutting for Stone is an unforgettable story of love and betrayal, medicine and ordinary miracles—and two brothers whose fates are forever intertwined.
