Fun, if not quite as fresh as the first book. Everyone's out to get Susan again, but it's a different set of baddies, and Susan is beginning to realize that her wish to live as ordinary a life as possible (why, Susan, why?) is drifting out of reach. She has some new, disturbing powers and puzzling dreams. As the book opens, Merlin's been sucked into a sinister fantasy map-world that combines the dozy heat of summer with grotesque, sometimes animated stone statues, and the booksellers of London need Susan's help to get him out.
Lots of action to follow, more police involvement and a higher body count than the previous book. Nix is very keen on describing what people are driving and wearing, and while I'm sure he did his research into 1983, I have no idea what a Ford Capri looks like, and nor do I care. Susan's fashion sense is eclectic, but she can't hold a candle to Merlin, who first appears in this book dressed as a Jane Austen character (not a male one, either).
I think Nix made a good call to end this series here. There are some showstopping scenes (Susan's meeting with a goddess, for one), but not a lot of emotional depth, and two books of having everyone trying to murder the main character is enough for me.
