I'm going back and forth between a 3 and a 4 with this one... 
 I know this is a series, but I just hate being strung along and then left feeling confused and incomplete at the end of a 400 page book. 
 BUT, as always, Stiefvater's writing is so weirdly poetic and interesting (not to mention intelligent), I typically err on the side of more stars. 
 So, here's four stars to a book that is unique and magical.
