Well I tore through that like there was no tomorrow. It's good. I need to read it again more slowly. I think I may need the audio version (which Neil as usual for his work narrates himself). It reminds me a bit of "Coraline" in that the protagonist is a child and that there's more than a touch of horror in the magic. It's almost a YA that's way too scary for YA. It's not my new favorite Gaiman but the more I read, the more it grew on me. I'll be back to this one for sure.
Update: I liked it even more as an audiobook. Neil's narration as usual was great. I felt that I got a lot more out it at the slower pace that audiobooks keep me at.
