A merciful promise

The job: infiltrate a militia amassing illegal firearms in an isolated forest community. FBI agent Mercy Kilpatrick is the ideal candidate. She knows Oregon. She?s near the compound. And having been raised among survivalists, Mercy understands the mind-set of fanatics. Lay low, follow rules, do nothing to sound an alarm, and relinquish all contact with the outside world. She?s ready to blend in.
