"An evocative panorama of America…on the cusp of enormous change" ( Newsday ) by the National Book Award-winning author of Ship Fever . In the fall of 1916, America prepares for war—but in the isolated community of Tamarack Lake, the focus is on the sick. Wealthy tubercular patients live in private cure cottages; charity patients, mainly immigrants, fill the large public sanatorium. Prisoners of routine, they take solace in gossip, rumor, and—sometimes—secret attachments. But when the well-meaning efforts of one enterprising patient lead instead to a tragic accident and a terrible betrayal, the war comes home, bringing with it a surge of anti-immigrant prejudice and vigilante sentiment. Andrea Barrett masterfully sets this luminous novel in a historical period of great progress in science and medicine—even in the art of war. Her richly complex men and women, with their passions and vulnerabilities, engage and haunt us.
