@KTB, I've read it awoke ago and I liked it. Your standard fair fantasy, a little above par. I like his second series The Red Queens War better. But, you should read the series in order as the overlap sort of, and take place in the same world. Definitely worth the read.
If your wanting something close to Banker, imo, try A Land Fit for Heroes trilogy by Richard Morgan. On my list, it ranks right below TSA. I don't know why I haven't tried his sci-do series, but I will.
