Alora: Witch Princess (The Majestics #2)

Alora is one of the five Possibles, a princess that may become the true princess of Citadel. In this world, one’s birthright doesn’t determine royalty. These Possibles were found, trained in their vibrance (magical energies), and took classes together in the palace; all in preparation for the Majo Majo Celebration. 

One night, Alora and the four princesses visit a traveling carnival. They soon realize each carnival attraction is a greatness test and they’re in the Majo Majo Celebration. The winner of the Majo Majo Celebration will determine who is the one true princess and will become the future ruler of the Citadel.
