Dark Predator: Number 22 in series by Christine Feehan
As brutal as the undead he hunted, Zacarias De La Cruz was a master executioner. Now his stark and savage journey is over. After a thousand years in a grey world, he has accomplished everything he set out to do - his brothers are safeguarded, and each has found a woman who completes Zacarias has walked the edge of madness. But without a hunt to define him, Zacarias wonders, for the first time in his life, who he really is. The answer awaits him back home in Peru, in the betrayal of a woman who is readying her trap, in the vengeance of an old enemy, in the inevitable consequences of a bloody family legacy, and in the deliverance of a lifemate he never could have imagined.
