Crosses to Bear. The Vatican Knights, #6

In a Galveston, Texas lab, a lethal strain has been stolen by a terrorist faction. In New Mexico, the population of a small town is completely wiped out. In Las Vegas, a vicious underground clan called the Community surfaces at night to prey on the weak. In Paris, two old foes of Kimball Hayden reunite as a kill team to hunt him down. Now considered dead by the Vatican, Kimball Hayden is leading a secretive life living on the streets of Las Vegas.
But when a parish comes under the threat of a vicious mob, he finds himself thrown back into a world of violence. Once again Kimball finds himself in the role as the 'priest who is not a priest' fighting to protect those who cannot protect themselves. And when Vatican City is threatened with complete annihilation, he returns to fight a battle against a foe he cannot possibly defeat.
