On the one hand, I really like this series, but on the other hand, I always forget what happened in the previous book before I get to the next one so I spend the first third going “oh, who is that?” “what are they?” “did that happen?” before enough happens in this book that I catch up and move on.
They’d probably be awesome read back to back, and what Chakraborty has done here with world building and non-western fantasy is absolutely fabulous.
