When petty thief Gilly, who lives with five younger brothers and sisters in a run-down boot, gets caught stealing, she is sentenced to three months at Fairy Tale Reform School, where all of the teachers are former villains, including the Big Bad Wolf, the Evil Queen, and Cinderella's Wicked Stepmother.

When Sleeping Beauty's nemesis breaks the Evil Queen out of the dungeon, Gilly and her friends at Fairy Tale Reform School must figure out how to stop Alva from terrorizing the village of Enchantasia--before she comes after the ones Gilly loves the most.

Gilly and her friends must prepare for a giant invasion after Jack plants magic beans, earning him a spot in Fairy Tale Reform School and reminding Gilly how good it feels to be bad. "Things at Fairy Tale Reform School are great. Rumpelstiltskin has been ousted, and everyone is buzzing about the fact that Beauty and Prince Sebastian (a.k.a. the Beast) have joined the teaching staff. Everyone, that is, except Gilly, who can't seem to focus on anything...

"The evil Rumpelstiltskin is planning to cast a curse that will erase Enchantasia as the world knows it, and a fairy prophecy declares that Gilly Cobbler will play a key role. Never one to shy away from adventure, Gilly and her friends embark on an epic, swashbuckling journey to stop Stiltskin from getting the ingredients he needs before it's too late." -- Provided by publisher.
