I read it last weekend, and really enjoyed it, but especially:

- I generally dislike talking animals as a concept, but I love the foxes
- Abigail's deep cynicism towards the police
- the translations of UK youth slang
- Abigail in general is just a really great character to spend time with
- Abigail's relationship with Nightingale, and his relationship with her family

I had trouble following the plot in parts, but that's because I tend to speed read these books, and usually fill in the gaps on a second read.
