Sanctioned Hitwoman

THE GOVERNMENT KNOWS ABOUT THE GRAY WOMAN...
And they are determined to use her unique skillset against terrorists and make her an offer she can't refuse.
When Homeland Security is alerted to threats against a retired army sniper made real with a bounty on his head, they offer the impossible task of keeping him safe to Julia Pelletier.

Kill teams arriving from the Middle East hope to collect on the death of Early Hollister.
But to earn the huge payday, supporters of ISIS must battle their way past the gray woman.
