Energy infrastructure around the world is under attack and cybersecurity super-sleuth Frank Adversego must solve a riddle with no apparent answer: when the only attackers capable of staging the assaults are also the targets, who can the attacker be? Part of the answer becomes clear as power plants, coal mines, refineries and tankers continue to be destroyed: someone – or something – has decided to single-handedly save the world from climate change. As Adversego closes in on his opponent, the attacker does the same in a race to the finish that only one of them can survive. "Andrew Updegrove brings a rare combination of drama, satire and technical accuracy to his writing. The result is a book you can't put down that tells you things you might wish you didn't know"
