And his partner’s murder is only the first in a series of meticulously planned murders carried out with all-but-impossible sniper shots. The only thing connecting the deaths is that the victims are all with law enforcement―that is until Page’s own family becomes a target.rnrnTo identify and hunt down this ruthless, seemingly unstoppable killer, Page must discover what hidden past connects the victims before he himself loses all that is dear to him.
