That one must be great.
I read that one in 2014, with the anniveresary of WW1. It's called The Sleepwalkers. How Europe entered WW1.
But what I wanted to comment is that, after having it for a while, I'm reading Don Winslow's The Border (I like Winslow novels a lot and have many of them. My favourites are The kings of cool and Savages, which was made into a film.), which feels as a sort of continuation of The Cartel. It picks up where that novel left off. But I think it's more concerned with the new heroin epidemic that has hit the US and Europe too since 2016-17. In the eyes of Winslow that is because the Sinaloa cartel decided consciously to move back to their origins in the 70s. In the case of Europe, which is served through Afghanistan I think it's because of the bumper crops they are achieving lately.
