Princess in Training.

I got this idea from a game on Roblox called Royal High.
Gloria is just a normal girl with some magic abilities, but when she least expect it, she is send off to a school meant for Princesses and Princes. She had no idea that she was a princess herself instill the headmaster tells her that she was the descendent of a magnificent royal family, but the bloodline was destroyed. Now attending a Royal High boarding school, her and her friend/room mate, Arianna, along with a popular Prince named Jason (who almost all the girls have a crush on) will have to survive this crazy and wacky magical school, and earn the title as Royal Princess/Prince.
