"Everyone here is already exposed. Don’t come here. Your family is dead. Your friends are dead. Do not trust anyone from the City. There may already be people out there who are infected and don’t know it. Do not let them in. Do not let yourself be moved by pity. They are deadly."

In the concluding novel of the After the Cure series, a small splinter colony of surviving humans struggle to protect themselves from a devastating plague. Without modern medicine, without electricity or hope of outside aid, the only resort is quarantine. But when even that proves not to be enough to protect the remaining healthy population, a tiny group of Infected race against their own bodies to destroy the Plague at its source.

The 40th Day is the fifth and final novel in the After the Cure series.
