It's 1941, and Canada is two years into World War II. Meanwhile, in rural Manitoba, fifteen-year-old Marie-Claire Cote begins a war of her own as she and her brother and sister, all stricken with tuberculosis, are taken by their anguished parents to "chase the cure" at nearby Pembina Hills Sanatorium. While her roommate retains a dogged cheerfulness that is both heroic and irritating, Marie-Claire resists with all of her prideful strength while she fights her own illness and tries to seek privacy where there is none. Her father, overwhelmed by fear and guilt, never visits. And her young brother, Luc, who is losing his battle with TB in another wing of the infirmary, sends notes to her penned for him by his nineteen-year-old roommate, Jack Hawkings. This is a story about surviving loss, and finding friendship, and love, in surprising places.
