On the island of Quill, anyone who displays artistic talent is Unwanted and sent to the Death Farm for execution when they turn thirteen.

When Alex and the other Unwanteds are dropped off at The Great Lake Of Boiling Oil, however, they are shocked to find themselves welcomed into the magical land of Artimè, created, hidden, and led by a mage called Mr. Today, with the help of his many staff.

Through this action, he attracts the notice of High Priest Justine and rises to the prominent position of her assistant secretary.

Then, due to a mistake on Alex's part, Aaron, Justine, and Governor Strang make a surprise visit to The Great Lake Of Boiling Oil and discover Artimè.

In the end, however, the people of Artimè defeat the Quillitary in a terrible battle and an uneasy truce is forged.
