I just finished Hex Hall (and on the EVE of DEMONGLASS to boot!), and I have to say that I REALLY, REALLY loved this book! Rachel Hawkins' writing in this work was just... effortless. I mean, I read a lot of YA and so many YA authors try SO HARD to sound so "totally hip and young and stuff, or whatevs [sic]" and I just really totally became lost in Sophie's story, and voice. The characters were great, and had lots of dimension, and there were some really nice twists and developments in the plot that really worked for me.
A new favorite for sure. :)
