Russ Allbery at Eagle's Path nails down exactly what's wrong with Blood & Iron, from my perspective as a writer.He's absolutely correct. It should have been in omniscient.
I didn't have the chops to do it when I wrote that book, or the balls to try. And frankly, I'm not sure I could have sold it in omni.
Whiskey & Water, on the other hand. I think I pulled it off for that one.
And I suspect Patience & Fortitude needs The Big Gun as well.
ETA And some ambivalence for the San Francisco Chronicle. I think he maybe wanted more horror in his fantasy.
