Forbidden Magic by Anya J Cosgrove

Beauty is vain. Beauty is dangerous.
The kind of beauty I found at Dark Falls Academy is deadly.
My sister Allie told me all about the sorcery classes, the potent potions, and the incredibly hot supernatural creatures that frequent Dark Falls Academy. Soon, I’ll be one of them.
Only my first day doesn’t go as planned.
Allie has been lying to me.
This school isn’t a dream; it’s a nightmare. Creepy shifters, brooding vampires, snarky mermaids, and vicious Fairy folk all want a piece of me, and they’re not willing to ask permission.
Flynn, the cruel bully.
Trent, the thirsty vampire.
And Cole, the dark Fae prince.
How I am supposed to kick their asses in the arena and in the classroom with all the mysteries and dangers lurking in the stony halls?
Dark Falls isn’t about good grades. It’s about survival.
