After being betrayed and captured by the most heinous survivors of the human race, B Smith lands back in the clutches of a fiend she had hoped to never see again, someone who is intent on making her suffer in the most tortuous ways. Discovering the fate of loved ones from B's past adds to the agony and calls into question just how much B is willing to sacrifice in the name of justice.
