I've read four of his novels so far, and they've all been thrill-a-minute page-turners. He doesn't write as much technical prose as Clancy, but his books are non-stop action the whole way.
Transfer of Power was one of the best recent books I've read, and
Term Limits was highly enjoyable.

In my opinion, he's still not as good as the master, but definitely worth reading if you're into that genre.
