A ruthless criminal's attack program threatens to expose classified government data. Worse, he has no compunction about killing anyone who gets in his way.

Rosa's sharp instincts, loyalty to her team, and courage to carry out the plan are paramount in working this case. But untangling herself from suspicion while actively working to bring a ruthless psychopath to justice may be more than she can handle...
