For Cleo Berry, the Spanish influenza devastating the East Coast feels far from the safety of Portland, Oregon. But then the disease comes west. Headstrong and foolish, seventeen-year-old Cleo is determined to ride out the pandemic at home rather than in her quarantined boarding school. But when the Red Cross pleads for volunteers, she can’t ignore the call. In the grueling days that follow her decision, she risks everything for near strangers. Strangers like Edmund, a handsome medical student. Strangers who could be gone tomorrow. And as the bodies pile up, Cleo can’t help but wonder when her own luck will run out.
