The Wall Street Journal bestselling series continues as Mercy Kilpatrick becomes embedded in the nightmare of a terrorist conspiracy.

The work: infiltrate a militia amassing unlawful firearms in an isolated forest community. FBI agent Mercy Kilpatrick is the ideal applicant. She knows Oregon. She’s close to the compound. And having been raised among survivalists, Mercy understands the mind-set of fans. Lay low, follow rules, do nothing at all to sound an alarm, and relinquish all contact with the outside world. She’s prepared to blend in.

As Mercy disappears into the winter season hills, something just as foreboding emerges. Mercy’s fiancé, Eagle’s Nest police key Truman Daly, is usually faced with a puzzling series of murders—three males dumped in random places after execution-style shootings.

Now, for Mercy, trapped in a tradition where suspicion can be second nature, and betrayal is usually punishable towards the extreme, there is absolutely no way out. No chance to demand help. So that as plans for the catastrophic terrorist event escalate, there may be no way to avoid them. Also if Mercy dies attempting.
