I absolutely LOVED the first two Hex Hall novels. There are few authors whose books I pounce on at midnight the day of release and stay up all night reading, so that should give you an idea of how much I love Sophie, Jenna, Archer, and Cal.
The relationship between Sophie and Jenna is still fantastic, and that was probably my favorite part of this book. Their worry for each other, their banter, etc, are all familiar and funny and a welcome interlude whenever they're together. There is also a plot line involving (view spoiler)[demon kids Nick and Daisy that pulled at my heartstrings a bit. (hide spoiler)]
