Hunter of Gunmen

Weaponized anthrax. So deadly a mere gram has over 100 million lethal doses, and terrorists are now in possession of it. When the world's intelligence agencies are unable to locate the extremists before they unleash their pandemic, governments turn to the Friends From Damascus. This rogue counterterrorist team will go anywhere and take any risk to deliver their form of justice to extremists. But this time the team faces an unexpected challenge from within its own elite ranks.
Their newest member, Katya Petrova, has lost all faith in humanity - the world's and her own. Her bleak and ravaged past as a Russian agent has destroyed her sense of self-worth. Before the team can hunt down the terrorists and the toxin, Petrova must learn to believe in herself again. Then she must earn the trust of the team's sniper, Joe Proffitt.
Outcast, mercenary, convict and founding member of Friends From Damascus, Proffitt's brutal life has taught him that all people are either hunter or prey. This former Marine and lone wolf trusts no one - so why should he trust scarred and hardened Katya Petrova?
