This book warms the darkest recesses of my blackened heart. A lot of reviews will point to the middle eastern influences and mythology as the reason you should look at this book (which are all very good points and are under-represented in this arena), but I put forth that you need no reason to check this series out other than Nahri - a clever orphaned con artisan that puts all other con artists to shame, and after accidentally summoning the djinn whose mere name is invoked to bring fear into all other djinn, she's fully unimpressed with him and his insistence that she's the last member of a venerated line of high-ranking djinn holy persons.
Everything else, from the complex political intrigue, the class wars, the intricate lore and hidden histories with all of the spectacular world building is beautiful drapery that gives this wonderfully memorable character a place to let herself loose and work her own special magic and weave her next con. I cannot wait to welcome her back in the next installation.
