"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 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 to a tragic accident and a terrible betrayal, the war comes home, bringing with it a surge of anti-immigrant prejudice and vigilante sentiment. Reading group guide included.
