Thy Kingdom Come (Sam Thorpe Series)
Don Helin

Colonel Sam Thorpe, a member of the anti-terrorist task force, must go undercover and train the Patriots, a homegrown militia in central Pennsylvania. His job: get close to self-appointed general Quentin Oliver and uncover the core of evil. Oliver, a disgruntled ex-Marine colonel, plans to steal cesium-137 from a local university and construct seven dirty bombs. During training sessions, Sam also uncovers a link between Oliver and the French Separatist Movement in Quebec. The world is in trouble, and Sam is isolated with only one person in his corner: FBI covert agent Alex Prescott, a kick-ass woman with spiked blond hair and a personality to match. Will she be enough? Or is the world about to realize its worst nightmare?
