Hex Hall (Hex Hall, #1)
by Rachel Hawkins
A fast, frictionless read was exactly what I wanted, and Hex Hall delivered. Derivative, but managed to pull off not just one but several nice plot twists and reversals.
I also have to award a point for the MC's lesbian best friend. I imagine there's fanfic about the two of them... it's too bad that, two days out, I can't remember either of their names.
I could see myself picking up the sequel the next time I'm feeling utterly lazy.
