King Hall (Forever Evermore 1)

King Hall — where the Mysticals go to learn their craft, get their degrees, and transition into adulthood. And where four new Rulers will rise and meet their destinies.
 
Lily Ruckler is adept at one thing:  survival.  Born a Mystical hybrid, her mere existence is forbidden, but her nightmare is only about to start. Fluke, happenstance, and a deep personal loss finds Lily deeply entrenched with those who would destroy her simply for existing — The Mystical Kings.  Being named future Queen of the Shifters shoves Lily into the spotlight, making her one of the most visible Mysticals in the world. But with risk comes a certain solace — her burgeoning friendships with the other three Prodigies: a wicked Vampire, a wild-child Mage, and a playboy Elemental. Backed by their faith and trust, Lily begins to relax into her new life.
 
Then chaos erupts as the fragile peace between Commoners and Mysticals is broken, and suddenly Lily realises the greatest threat was never from within, and her fear takes on a new name: the revolution.
