Clancy-esque Techno-Thriller Recommendations?

Howdy everyone!

When I was a teen, I was very much into the original run of Tom Clancy novels — The Hunt For Red October, Red Storm Rising, Patriot Games, Cardinal of the Kremlin, Clear & Present Danger, and Sum of All Fears… as I grew older, however, I felt like he pretty much became a book mill, and his style declined.

I recently went back to read some of his original stuff, thinking it would be much better than it was, and while I still love the scenarios and cutting edge technology, found his characters to be dry and dull and his prose clunky, at best. It seems to get progressively worse as his books go on, with his characters increasingly becoming cardboard cliches. I feel like he put honest effort into his first few, and might have actually improved as a writer if he'd been more interested in writing compelling books rather than just collecting paychecks.

In retrospect, I see now why his stories still make for (relatively) better film and television adaptations than books — the screenwriters can eliminate the clunky prose, dispense with the cliches, and the (right) actors can inject the characters with more depth than they otherwise had in the books.

Anyway, I was wondering if there was an equivalent to Tom Clancy today, a writer of techno-thrillers with interesting, compelling characters, scenarios using real world (or close to real world) technology, and an overall better writing style.

Thanks in advance…
