Beastly by Kiera Legend

Welcome To The Citadel
Kit never planned to attend the Citadel, the exclusive Academy her parents sent her to. To make matters worse, she finds out there are a lot of rules—and she plans to break them all to be kicked out.
Problem is the headmaster has no intention of letting her go, because there’s a reason she’s been invited.
The Citadel is a school unlike any other, and Kit soon realizes there’s a new whole world inside its walls. A world made of shifters – and she is supposed to be one of them. What the hell?!
Weirdness takes over her life as she meets all kinds of monsters and beasts she never thought existed.
But something even more dangerous lurks behind the doors of the school. A danger that could destroy them all.
With the help of a hard-partying, jock vampire, a werewolf student activist, and a tech-savvy artist angel, Kit will break even more rules in the attempt to solve this mystery.
But what if the three of them fall in love with her in the process?
