Wolf Moon by Lena Mae Hill

All Timberlyn wants is to get out of her small town, where she’s branded a freak just because she happens to wear all black and draw gruesome monsters in her notebooks.
When a letter arrives saying she’s been accepted to the mysterious Ravenwood Academy for the Exceptionally Gifted, she jumps at the chance. Never mind that she’s not sure what she’s supposedly gifted at, or the fact that she doesn’t remember actually applying there.
When she arrives, the school seems like a dream full of beautiful people ready to befriend her. There’s only one problem with Ravenwood: it’s run by Alarick Wolf and his brothers, three surly, thuggish, insanely gorgeous guys. Timberlyn’s new friends give strict instructions to stay far away from them.
Unfortunately, she’s not good at taking orders.
When girls at the school begin disappearing, Timberlyn refuses to maintain the status quo. She’s sure Alarick and the Wolf boys are up to something, and if she has to, she’ll take them down herself.
That is, if they don’t take her down first.
