Overlong, and thinks it's smarter than it is-but this is Libba Bray, and all of her books (that I've read) are like that. 
 She captures the 1920's very well, and bringing a period to life is one of her greatest gifts. Also, the pacing was pretty good for such a long book. 
 On the downside, this novel also had the stereotypical elements of all current YA novels: predictable, boring, overly sentimental love interests/elements, annoying or token characters, rushed endings and underwhelming climaxes, unecessary sequel lead in, and a villain who lost his scare-power way too early. 
 I could go on, but suffice it to say, I won't be slogging through any sequels.
