Calonita, Jen. Royal Academy rebels.

"Princess Devin didn't come to Royal Academy for fame, glory, or a crown. All she's ever wanted is to be a Magical Creature Caretaker. Just when Devin gets up the courage to ask about following her passion, disaster strikes. The evil Rumplestiltskin and Alva cast a curse that nearly destroys Enchantasia, a new villain is on the rise, and the students of Royal Academy find they now have to share their castle with the delinquents from the notorious Fairy Tale Reform School. Devin feels stuck--how can she think about going her own way when her kingdom clearly needs her now more than ever?" -- Amazon
