Excellent story, well told. I love a good historical that jumps right into a real event and weaves a plausible tale around what few facts exist, and this certainly does that. I was pleased to meet Ryzhkov again and be drawn into his world, and to learn more about the chaotic swirl of events surrounding the Russian Revolution(s), the simultaneous First World War, and the fate of the Romanovs.
Miller's technique includes a rapid switching of POV among his characters. This is something that I can quite like when well done, but can be just annoying when not. It works quite well here for the most part, although there was one point in the climactic shootout where I had to go back and re-read to figure out who had just been wounded. But then, when I get excited by a passage, I tend to read faster, so....ha.
Very satisfying. Keep writing, Miller!
