Agent Jamie Dallas loves undercover assignments that get her out of the Phoenix Bureau. But when a woman and her baby disappear from an isolated community of preppers in Northern California, she knows the risk of infiltrating the armed group is dangerously high. Once inside the compound, she discovers that the brothers who founded Destiny are scheming something far more devious than kidnapping or murder. Meanwhile, her local FBI contact, Agent McCullen, is pulled from her team and assigned to investigate the murder of a woman with phony ID, found at the bottom of a motel pool. Soon Dallas finds herself in deeper trouble than she's ever encountered—with no way to reach her contacts. Can she break free of the bunker and stop their bizarre end-of-world plans? Will Agent McCullen identify the killer in time to help? The Trigger is a gripping story that highlights our greatest fear—how a megalomaniac and a hacker-for-hire can threaten civilization as we know it.
