I'm waffling on this one. There were some really good parts (most of Myfanwy—Amber has given me a residual love of protagonists with memory loss), some bad parts (half the book was info dumps that went from an interesting plot device to clunky and interrupting), and some parts that just don't make sense when you think about it too hard (the plot). Overall it was quite a lot of fun, though. Reminiscent of the Laundry Files.
