Amazon.com description: Product Description: Even the deadliest gangs in Chicagoland fear the Cross Crew and carefully avoid their cinderblock bunker headquarters: Red 71 is well known as the last place you'd want to go . . . unless you’re willing to risk it being the last place you'll ever go. The Crew is notorious for its ruthless efficiency and cold-blooded cunning. Why, then, would anyone be foolhardy enough to threaten them–and even more dangerous–their loved ones?
 
As Cross catches the scent of a far-reaching conspiracy, he realizes that it all connects to an unexplained event in his past: a massacre from which he emerged inexplicably unscathed, save for the blue mark on his face that pulses when danger is near. That scar has been throbbing more frequently of late. . . . If he's reading the signs accurately, Cross might find himself again facing a terrible menace that is not altogether human.
