Book 4: Fairy Tale Reform School
 
The fourth installment in the beloved Fairy Tale Reform School series where the teachers are (former) villains
Reform or relapse?
Things at Fairy Tale Reform School are great. Rumpelstiltskin has been ousted, and everyone is buzzing about the fact that Beauty and Prince Sebastian (aka the Beast) have joined the teaching staff. Everyone, that is, except Gilly, who can't seem to focus on anything but Anna. How is it that her beloved sister somehow went bad and joined up with Rump? And why doesn't anyone seem to care? Sure, the Royal Court says they're working on it, but they've got exactly nothing to show for it.
