Dark Fae by Caroline Peckham

What do a heartless Dragon Shifter, a cold-blooded Basilisk, an arrogant Lion Shifter and a brooding, tattooed Harpy have in common…?
Me.

Elise Callisto. Vampire. Angel of vengeance. And a girl on a mission to destroy one of them for murdering my brother. I just don’t know which one did it yet.
When I kicked the ass of a Werewolf who was high on a new and dangerous drug called Killblaze, his final words painted a dark reality for me. The King of Aurora Academy killed my brother. The trouble is, there’s four kings at that school and each of them have motive and cutthroat natures.
Aurora Academy isn’t a place for the faint of heart. To put it lightly, my town is the asshole of Solaria where the dodgiest Fae in the kingdom reside. The school itself is divided by the two gangs who run this town. The Lunar Brotherhood and the Oscura Clan. And guess what? Two of the kings run the gangs at the school, their hatred for each other so fierce I hear a day doesn’t go by without blood being spilled in the halls.
I might be a petite, lilac-haired girl who looks like a fragile doll, but they haven’t been introduced to my fangs yet. And they don’t know why I’m really here. Or that I’ll do whatever it takes to bring down the Fae who took my flesh and blood from me.
I don’t believe in fate, but I do know this… the King who killed my brother is a dead man walking. And I’m prepared to sacrifice my heart, body and soul to ensure I get my revenge.
