The Assassin and the Deer — Diane Weyer

Tessa works as an undercover agent for the Organization, the top-secret arm of a human rights group. When her Boss informs her that a man has breached the security of their communications network, she accepts her assignment to terminate him. Down mountain roads at terrifying speed, through hostile terrain on foot in complete silence, eluding men who will torture and murder, she moves in for the kill as the story races to its conclusion.
