In the novel, Patrick McLanahan, a recurring character in Brown's books, returns from overseas conflict to his hometown, Sacramento, California.
There he encounters an old enemy whose evil plot forces McLanahan to take a terrible chance as he employs experimental technology to make himself a human weapon.
Using BERP armor, and (chiefly) nonlethal weapons, he attacks methamphetamine-producing biker gangs, after his brother (a rookie cop) is severely injured.
This stands for Ballistic Electro-Reactive Process and was developed by Doctor Jon Masters, another recurring character in the McLanahan series of books.
