I haven't read his other stuff (is his writing style fairly consistent?), but I have read the Star Risk novels and, as said above, they are a brainless, over the top, sex/guns/massive explosions romp that is most likely the best written crap I have ever read (and I mean that in a good way). They don't have any real substance and his new one -double cross program is the name I remember- has so many blind turns and twists that I'm surprised he can keep it all straight. Honestly though, if you don't want to read a heavily thoughtful novel, they're great and not in a 'gloss over all the badly written portions' way.
