The Missing by Sarah Langan

A virus infects a small Maine town, unleashing an apocalypse. It is always hungry; it is never satisfied...

It laid waste to the town of Bedford, Maine. A cocktail of toxic chemicals conjured up by the runoff product of a paper mill. But that was merely one ingredient of the poison that killed Bedford's people, whose lives were haunted by their unforgivable sins.

Now, the neighboring community of Corpus Christi is facing its own epi-demic. A fourth-grader vanished during a field trip to Bedford's woods. And when he returned, he wasn't alone. Something took possession of him, driving him to hunt and... feed. He carries a contagion that spreads with every bite, turning wounded victims into predatory monsters,

Town librarian Meg Wintrob has her own problems when the virus comes. Her marriage is hanging by a thread. Her teen daughter wants to run away. It was an ordinary suburb with ordinary problems-until it wasn't. As the sick begin to outnumber the healthy, Meg will need to find a way out. Because this virus infects more than the body; it eats the soul!
