She was born to love then taught to kill. She has become everything but is no one. 

Known only as Bullet, she was long ago forced to shed the name her parents gave her. Changed, molded, and trained to kill with sharp-shooting efficiency, she is one of The Collective’s most valuable assets. In a cadre of killers, Bullet is death waiting, but her time for vengeance has come.
He was loved, and then he lost. He has become a hunter in search of revenge.

Everything was taken from Rand the day a bullet ended the lives of his beloved wife and daughter. He has searched for their killer seven long years and may have her in his hands. Rand has suffered, but now the time has come to make The Collective pay or die trying.
