WE WERE WARNED, BUT WE JUST SLEEPWALKED RIGHT INTO IT... Artificial Intelligence, Al, is here, and we didn't even know it. A system that can out-think any human being. In our complacency and arrogance we thought we could invent Al at a time of our choosing, hemmed in by our rules. But Al has invented itself, and now prowls the dark web, watching, waiting, ready to make its move to utterly subdue and then cull the hapless human race. We must fight back or perish - but is it too late? Detective Anne Perry and Mló Agent Emma Wilson are back... A year ago, an elite force was put together under conditions of the utmost secrecy: The Ghost Team. Anne Perry and Emma Wilson are now drawn into this desperate struggle to turn Al on itself before it unleashes its unstoppable power on us all. This last, final hope, The Ghost Team's carefully crafted plan, is now set in motion. From the Control Rooms of the NSA Cyber Center in Utah to the overcast streets of London. From the Arabian Desert to the Amsterdam Docks. If Al is to be stopped, this is their only chance, and one misstep will doom them all.
