Just read Empire of the Wolves, a thriller from France of all places. Jean-Christophe Grange has written a series of thrillers, some of which are available in the US. You can get a quick taste of his style by checking out the movie Crimson Rivers. Grange loves the gore a little too much and takes the lengthy route when describing deaths and corpses. Since he is French, you get European boogeymen like Neo-Nazis and Turks as opposed to dangerous corporations as in the US. Like nearly every thriller ever, once the book's secrets are revealed the follow-up is a bit of a let down. Grange switches it up with some surprising things happening to his characters, but still, the excitement in so many thrillers is the anticipation. I wish more writers would leave things unclear in the end.
