This series is pretty disconnected from the first 5 books but does connect up with later books. It follows Azar an ifrit (a kind of djin) who is hiding out from other djin in New York City as a firefighter. The series was ok, I ended up DNFing halfway through the second book because Azar kept making stupid ass decisions which always irritates the crap out of me. Not bad just kind of disappointed, might go back and finish idk.
