The Cyber Solutions team has managed to stay one step ahead of the madman who has killed so many. From the original 26 Below cyberattack in Fairbanks to the 8 DOWN serial murders in Anchorage and beyond, they matched wits with the killer and stopped him from reaching his ultimate goals.

But final judgment is coming. And this time, there may be no defeating him.

David “Mac” McPherson has a personal stake in making sure this predator stays down for good. His family died in the cyberattack. Mac knows that God says “vengeance is mine”—but surely an exception can be made.

Surgeon Tracie Hunter is determined to stay sober and keep saving lives in Fairbanks, Alaska—even if it means being a little obsessive. After all, that same kind of determination is how she kept Mac alive after the murderer targeted him.

And she won’t let Mac run himself into the grave looking for payback; he’s come to mean too much to her.

Then someone hacks into the system at Tracie’s previous job and frames her in a murder cover-up. There’s no one else skilled enough to create a digital trail this incriminating—the killer is back in action, exploiting cybersecurity weaknesses to destroy lives. Can Mac stay focused and stop the next attack?

Or will his need to make someone pay for his pain allow the maniac to pull ahead and win at last?
