Mask of the Serpent by S. W. Vaughn
No matter who loses, the bad guy wins
Drug lord and self-professed saint Diego Mendez is a man of his word. He's watched two of his lieutenants die, thanks to Angel and House Phoenix. Unfortunately, he's promised a certain crooked cop that he won't seek revenge unless Phoenix hits him first. When Angel makes a run on his turf, Mendez decides it's enough of a loophole to act. He kidnaps Angel's lieutenant, Jenner, intent on breaking him-and killing him.
But Jenner is just as nasty and mean as Mendez, and breaking him is no easy task. His secret past has conditioned him for survival at any price. And Mendez has a secret of his own-his son is dying, and he's been reduced to watching helplessly while it happens. One of them will triumph, one will fall. But in this game, no matter what happens...the bad guy wins.
Contains violence, nasty language, and torture.
