Come to Dust - MacLeod Bracken

Ever since her mother abandoned her, five-year-old Sophie has had to depend on her uncle Mitch for everything. Though their life is difficult, he works hard to keep their family together, despite the obstacles in their way. But just when everything seems to be looking up for them, it all comes crashing down when Sophie dies tragically. Mitch descends into a crippling grief, not knowing how to continue on without her.

When scores of children around the world begin to inexplicably rise from the dead—Sophie among them—everything becomes much harder.

Mitch rescues her from the morgue, determined to carve out a normal life for them no matter what, though it soon becomes clear that may not be possible. While the kids who’ve returned behave like living children, they still look very dead. And they can do something else that normal children cannot. Something terrifying. While debate rages over whether the children’s return is a mercy or a sign of approaching judgment, a congregation of religious fanatics determined to usher in the apocalypse has its own plan for salvation.

Now Mitch must find a way to save Sophie from an increasingly hostile world that wants to tear them apart and put her back in the ground for good.
