If the criminal underworld elements are what you're most excited about from Shadow and Bone and Six of Crows, then you should definitely be reading The City of Brass by S.A. Chakraborty. Nahri is a young con woman who knows the streets of 18th-century Cairo better than anyone. When she accidentally summons a djinn, Dara, during one of her cons, though, everything gets thrown into chaos. She's forced to go on the run with Dara, and they head for the legendary city of brass: a city steeped in legend and magic — with an ancient war ready to spark into a flame.
