This has been a fascinating trilogy to read as it blends fantasy and sci-fi to create a world where magic powers advanced machinery but also imbues people with strength and special powers.  Mix this with aspects of African culture and characters that are complex and personable and you have a unique and bewitching story that you don't want to put down. 

This novel leans more towards the sci-fi aspect than the previous books and introduces more locations and characters which all combine to weave a spellbing tale that delivers a satisfying ending to the trilogy, while also leaving the door open to revisit this world and characters in the future.
