As they recruit new killers into their ranks and more innocent people linked to the initial murders are killed it becomes clear that Wallace is dealing with an unprecedented threata deadly alliance formed to terrorize the nation with coordinated strikes. With the killers always one step ahead, the very fabric of society threatens to unravel and Wallace battles to decipher The Alliances endgame before they dismantle civilization city by city. In a desperate race against time, can Wallace uncover the members and motives of the Alliance and end their reign of terror before more victims wind up dead.
