Zodiac Academy Series by Caroline Peckham and Susanne Valenti

Series Blurb:

I’m a Gemini. Impulsive. Headstrong. A twin. And apparently… Fae.

As the daughter of the Savage King, I’m heir to a throne I never knew existed—and I’m not the only one. My twin sister and I have been dropped into the deadly world of Solaria with one goal: prove we’re the most powerful supernaturals in the realm.

Sounds simple, right?
Wrong.

Zodiac Academy is a brutal school where your star sign determines your magic, and power means survival. Vampires bite in broad daylight, werewolves host orgies under the full moon, and Sirens manipulate emotions like puppeteers. And my biggest problem? The Dragon shifter who’s got his eye on my throne—and a grudge to match. He and his three savage friends have made it their mission to break us.

But I don’t back down.
I fight.
Even if this academy is designed to crush me.

The 12 Book collection includes books 1-9, The Awakening as told by the boy, Live and Let Lionel, and 8.5 Beyond the Veil.
