When it happens, it happens quickly. New England is locked down, a strict curfew the only way to stem the wildfire spread of a rabies-like virus. The hospitals cannot cope with the infected, as the pathogen’s ferociously quick incubation period overwhelms the state. The veneer of civilisation is breaking down as people live in fear of everyone around them. Staying inside is the only way to keep safe. But paediatrician Ramola Sherman can’t stay safe, when her friend Natalie calls – her husband is dead, she’s eight months pregnant and she’s been bitten. Ramola is thrust into a desperate race to bring Natalie and her unborn child to a hospital, to try and save both their lives. Their once familiar home has become a violent and strange place, twisted into a barely recognisable landscape. What should have been a simple, joyous journey becomes a brutal trial.
