Alexandra I totally recommend the Shadow Falls series, because it's similar to the plot in Hex Hall: Kylie Galen is sent to a camp for 'troubled teens', where she finds out she's not completely human. At first she thinks everyone is just crazy-acting-strange people but when she starts learning more about herself, she realizes everyone there, inluding herself,has paranormal abilities no human can have. She becomes best friends with her roommates, Della the vampire and Miranda the witch, and finds herself between two boys that have clearly stolen her heart, while trying to figure out how she is special.
Maddie S You could try reading, "Beautiful Creatures" if you haven't read it. Or you could read "The Mortal Instruments" Both are dark, but decent series. They are each in this genre. Or, if you want a more whimsical book, a fun choice is "Howl's Moving Castle" the original book. It's good. :)
