A very strong 4.5 for this. Dogs of War was my introduction to Tchaikovsky's work and I rated it very highly. This unexpected (to me) follow on delivers on every front.
What I like in particular about this series as opposed to other stuff of his that I have read (all high quality) is the directness. These books don't faff about with sections of zoological musings which I feel detract (slightly) from the story.
Although this story has a Trump analogue as the antagonist, something I feel that is going to be common for a while, it is appropriate and well done.
Punchy, gritty entertainment of a very high quality. Recommended.
