After watching her sister die at the hands of a vicious killer, Jane Piper received an invitation. She answered it.
At twenty-eight she became an assassin, a hunter for Gatehouse, the secret organization that stands between life as we know it and the most ruthless killers the world has ever seen.
They’re called Sacks. And they’re changing . . .
Now, two years later, these killers are slaughtering innocents as never before, carving a path of terror from New Mexico to Montana. Most disturbing of all, they’re cooperating with one another for the first time. They have a mission.
Staying alive means knowing who is on your side . . .
In a desperate race to uncover that mission, Jane must battle those whose sole purpose is to stop her from discovering the truth. Targeted for elimination by an unknown figure, and facing betrayal at the hands of those whose loyalty she never doubted, Jane begins to question her most deeply held beliefs.
What she discovers will change her life forever.
