Jake Tanner is tormented by memories of the people he’s failed to save. Hoping to give his spinning mind a break, the detective treats his wife and kids to a fancy meal in London’s tallest building. He never expected that his family time would be cut short by a biological terrorist…
Cut off from outside help and struggling with his PTSD, Jake may be the only man who can save the hostages and thwart the horrific attack. As a deadly game of cat-and-mouse begins, the detective must conquer his own demons to outwit a deranged mastermind. If he fails, the airborne pathogen's devious purpose will decimate humanity's future.
Can Jake defeat a savage psychopath before the bomb annihilates humankind?
