It really doesn't matter what I say below because really, you should just read this series because of the unique New York of Vampire/Minority/Immigrant politics in the roaring 20's complete with feisty female reporters, djinni, mystery, speakeasies, non-European main characters and mafia.
And also because the heroine, Zephyr Hollis is one of the most human main characters I've come across in a long time. Human (despite her strange and disturbing immunity to vampires) because she's conflicted. She does hypocritical things like lobby for prohibition of vampire Faust (liquor) while drinking at speakeasies. Although she grew up as a fight-trained killer of demons, she's gotten soft and now she gets surprised by bad guys conking her over the head. Her favorite choice of problem-solving is avoidance, and while her heart longs for the djinni Amir, she isn't afraid to speak on those feelings even when she's unsure.
But as much as I like Zephyr and Amir, and their lovely "I'm going to save him/her for his/her own good without letting on why I'm acting this way" romance, the book is just a bit uneven. This was my problem with the first book in the series, too.
There's so much plot crammed into this story, its coming out of Zephyr's ears. There's the Amir-saving, the dodging of the policemen investigating her for underage vampire harboring (from book one), helping Elspeth with the anti-Faust campaign, investigating an anti-Vampire lobbyist named Madison, figuring out why vampires are dying, figuring out why her dad has gone crazy, etc. etc.
It gets confusing.
Also there's some tiny, nit-picky editing issues I was disappointed to see in a professionally published (I also read Indies an am more forgiving there) book. Really, just nitpicky, but they kicked me right out of reader-mode. (For example on pg 53 "Amir had offered to get me a new bicycle, but I had decaying for the same reason I refused to ask for a pair of dancing shoes." decaying?)
But really, as I said before, you should read the series anyway because its so *fun*. And I'm definitely going to read book three (there better be a book three) just because of the set up for Zephyr's importance in the grand scheme of vampire-world at the end of this book.
