I loved the awkwardness and self confidence of Nathaniel. The steam-punkish jinn infested London - brilliant! I don't know why but fantasy set in London is just wonderful - it is the most wonderful city for dark, grim and mysterious fantasy. The moods are so that you can smell the city at times. The relationship between Nathaniel and the jinn is so enjoyable. It makes me smile and want to read it again to think about it.
