The Empire of Gold is the end of the Daevabad Trilogy (which includes The City of Brass and The Kingdom of Copper). I admit when I picked up The City of Brass I didn’t much care for Nahri. It took me well over a year to decide to keep going with the series and pick up The Kingdom of Copper. S.A. Chakraborty grew a great deal as a writer between those two books, and more again with The Empire of Gold.
