When someone wants to find you badly enough, vanishing is no longer an option.

Sarah Keller is a young single mother living in Oklahoma with her five year-old daughter, Zoe. Her day job is to hunt out people on the run and bring them to justice. So imagine how it looks when a school bus accident sends Zoe to the ER and tests reveal Sarah can't be Zoe's mother. Sarah has been living a lie for years and finally the truth is coming out. Who is she? Who were Zoe's parents? And why does Zoe's identity bring the FBI down on Sarah's tail in mere minutes?

The FBI is the least of her worries, though. Sarah needs to keep Zoe off the grid, but with a sinister religious cult also on the trail, where on earth can they hide? Something deadly lurks in Sarah's past and its resurfacing brings terror to all it touches.
