(The fourth book in the Nick Hall series)
A novel by

Return to the breathtaking series that has earned over 15,000 five-star ratings.

Nick Hall is the ultimate operative, having brought tyrants, warlords, and terrorists to their knees. His unique brain implants allow him to wield the Internet with his mind and pry into the thoughts, secrets, and memories of the most despicable people alive.

After a near-fatal clash with Troy Browning, a cunning psychopath and one of only three mind readers on earth, Hall faces the most daunting threat of all. Because Browning has found an ally as ruthless as he is. A genetically-engineered titan whose physical and mental abilities dwarf those of ordinary men. Together, the pair plan to create an unbeatable army. Their target? Humanity itself, starting with Nick Hall and those he holds dear.

Hall is soon thrust into a relentless battle for the future, one that will test the limits of his ability. As the surprises mount and the stakes skyrocket, Hall is forced to confront a chilling reality. If he takes one wrong step, he won’t save humanity—he’ll hasten its extinction.

Based on actual research on neural implants and controlling the Internet with thoughts, the
Nick Hall novels are pulse-pounding thrillers packed with deep insights, nonstop action, stunning revelations, and roller-coaster twists and turns.
