Lost Immunity

A thrilling novel that will keep you reading into the night


An ordinary day
Seattle is stunned when a deadly bacteria tears through a nearby Bible camp. Early tests reveal it is a form of meningitis, and the camp’s residents are among its most vulnerable victims: children and teenagers.

A new vaccine
Seattle’s chief public health officer, Lisa Dyer, and her team quickly take steps to contain the outbreak. When testing reveals the strain is one that caused catastrophic losses in Iceland just months earlier, she contacts a pharmaceutical company doing final-phase trials on a viable vaccine and asks them to release it early.

An epidemic in the making
Despite protests, vaccine clinics roll out across the city, and the risky strategy appears to be working. Until people start dying from mysterious and horrific causes . . .
