In Lethal agent by Kyle Mills, Vince Flynn’s Mitch Rapp is on the trail of a French microbiologist, who has been kidnapped and forced to manufacture anthrax by ISIS.  The trail leads to Mexican border, where a drug cartel is hired to smuggle the bioweapon into the US.  Rapp infiltrates the cartels to learn the identity of the Is cell behind the plot.   This one is suitably timely for paranoid thrills.
