I recommend Hex Hall. 
 ***** 
 Hex Hall is such a fun read! The story is somewhat unique once the twist was thrown in. Never mind the pop culture references or the shallowness of a boarding school (some of it, anyway). I really enjoyed my time reading this. =) 
 Sophie is very entertaining to read. She's sassy, defiant, and downright sarcastic. Archer (man, i love that name) is my typical bad boy: arrogant and confident. It was refreshing to see how Hawkins build their relationship. You all know i am not a fan of love-at-first-sight stuff, right? So the gradual change of Sophie's and Archer's relationship from being frenemies to friends to what-am-i-to-him-? was so fun. And whatever happened to cellars being so scary? That cellar scene was hot! 
 The legend on how the Prodigium started was intriguing. There's a lot of magic that's wasted on petty quarrels so i didn't like that. But when the time came for Sophie to be a dark witch (or whatever she was), she pulled if off flawlessly. Hello, there's no hesitancy when she killed the demon. Very nice! 
 Hex Hall is exactly the light read i was in the mood for. The romance was okay, but the paranormal part was not bad, either. Try this out while i go on to read it's sequel, Demonglass. =)
