The Turing Test, a Tale of Artificial Intelligence and Malevolence by Andrew Updegrove

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 by whatever means it takes. As Adversego closes in on the attacker, his opponent closes in on him in a race to the finish that only one of them can survive.
