Delusional — James Patterson; James O. Born

Detective Michael Bennett and army-sniper-turned-NYPD-officer Rob Trilling travel to Montana to investigate a case that crosses state borders and family lines.
 
In New York City, a series of deadly bombs explodes.
In New Jersey, a military base is burglarized for explosives.
In Montana, violence and arson rock a small town outside of Bozeman.
Are the incidents related? Bennett, Trilling, and the ATF investigate.
A single-minded group angry with the government keep turning up in unexpected places, insisting that they're only trying to make the world a better place.
To law enforcement, their claims seem delusional.
Will words or gunpowder light the next fuse?
