A month later, on a sleepy Sunday afternoon, medical examiner Sara Linton is at lunch with her boyfriend Will Trent, an agent with the Georgia Bureau of Investigation. But the serenity of the summer’s day is broken by the wail of sirens.

Within hours the situation has spiralled out of control; Sara is taken prisoner; Will is forced undercover. And the fallout will lead them into the Appalachian mountains, to the terrible truth about what really happened to Michelle, and to a remote compound where a radical group has murder in mind…
