Hexbound (Dark Elite, #2)

Lily Parker is new to St Sophia's School for Girls, but she's already learned that magic can be your best friend ...or your worst enemy. So they say absolute power corrupts absolutely. But it turns out even a little bit of magic can turn you to the dark side. That's why Lily has to learn how to control her newly discovered abilities and quickly, on top of avoiding the snobs who think they run her school, nursing a crush on a cute sophomore with a big, werewolfy secret, and fighting the good fight with her best friend Scout as they take on Chicago's nastiest nightlife - including the tainted magic users known as the Reapers. All that's even before Lily's invited to a private meeting with Sebastian. He's hot, he's powerful, and he's offering to help her harness the magic flowing through her veins in a way that no one else can. He's also a Reaper. Lily can't help but be suspicious of his offer. But she also needs his help. It seems that the line between good and evil isn't quite so clear as she thought ...
