I'm not sure this was completely a 5 star book, but it was definitely a 5 star reading and I enjoyed it tremendously. My reservations about the book are kind of vague in any case and have to do with possible implicit racism, but it's more of a feeling than a reasoned argument. (I will be googling to see if I can find any reasoned arguments, however.) At any rate, it's no worse than what you'd find in many fantasy books or movies. Anyway, fantastic plot, intriguing characters, great setting -- how often do you find a YA book are set in Prague?! I can understand why some people found the second half disappointing and I did at first, but it all unwound so fabulously that I changed my mind. Dying for the next one.
