It's funny, I find I don't have much to say about this book, even though I quite enjoyed it - hence the late review. Perhaps I don't have any strong feelings about it, either positive or negative, and I'm afraid the rating rather suffers because of this - let me just say, the rating does not reflect the addictive quality of this story, because it sucked me right in and I was very annoyed when it ended and I didn't have the sequel in my hands yet. 
 I have a few grievances regarding the writing, but nothing that interfered greatly with my enjoyment of the story. I liked the characters - especially Kell - but am not head-over-heels in love (yet). The plot was original in many ways, but in some ways not so much (but can I just say a major hurrah for multiple Londons?????). My favourite character might be Astrid Dane, because I'm weirdly into sadistic villains (I am also quite fond of Bellatrix). I may also be biased because I am a Dane in the sense of the country and it felt like White London had a Nordic/Scandinavian vibe going on ;) But I don't feel I got to know a lot of the characters very well in this story, probably because it takes place in the span of two days or so, and I hope that will change with the sequel - hopefully I'll also develop stronger feelings about this trilogy when I get a little further! 
 As a final note, it is apparently adult fantasy, but it feels more like YA in terms of writing. I am told it will feel more adult in the sequels, so I'm looking forward to that. But it genuinely is an addictive and enjoyable read, so do pick it up if you're intrigued by the premise!
