This was the weakest of the three books that are out so far. The narrative was inconsistent and even boring in places, a word I could not have previously imagined using in relation to this series: too much talking, not enough happening. The "twists" were obvious from the moment the antagonist was mentioned. And Valente introduced too many weird new fairyland things - another criticism I wouldn't have expected to use on a series I was drawn to because of its hyperfantastical nature - that were utterly forgettable without bringing back any of the characters I loved from the first two (except of course the two deuteragonists Saturday and A-through-L). The only new character I thought interesting, the blue wind, promptly disappears after the first couple of chapters and only makes a brief reappearance later. 
 Still likable, but if this had been the first book, I wouldn't have picked up the second.
