This series is basically if ASOIAF was based in Chinese history instead of British, but with Neal Stephenson's fondness for "technology!" and Django Wexler's deep empathy for his characters.
It's also completely its own thing, but if you like any of those, this series is such a good read.
Also this book was like 700 pages of deep existential questions about the nature of cultural identity and conquest and what is right for a ruler to do and then 300 pages of the Great Dara Bake Off and part of why Liu is SUCH a compelling writer is that I loved both. (There are literal actual dragons in this book and they are fundamentally less interesting to the text than the bit where someone invents the instant pot and I cannot tell you how much glee I had.)
Like so many epic fantasy series, this duology is getting rather long, but Liu promises the next book will be the last and I'm very much looking forward to it.
