Underneath the city of Springfield, Missouri, in the caves and tunnels around downtown, lives a dark community all its own. And as Detective Booger McClain discovers: above ground isn't much different. As McClain searches for answers in a famous local homicide case, he and his wife, Rose, run straight into his old nemesis, The Order, a secretive group of wealthy men who hold tremendous power and influence. And this time, The Order is hellbent on destroying the nosy Ozarks' detective for good before he learns too much.

Will what's hidden in the darkness stay hidden? Will the light of truth win out in the end? When even good friends are foes, who can Booger turn to? Luckily, McClain has an ace up his sleeve. Nobody messes with Rose's man.
