The city of Quill is messed up. I'm just going to say that. Their one 'holiday' is sorting people by whether they're wanted, needed, or unwanted (ouch!) called the Purge. Our main character is Alex Stowe who is Aaron Stowe's twin- and an Unwanted. Then we have all Unwanteds handcuffed and sitting on a bus going to The Great Lake of Boiling Oil.
However, unknown to the High Priest, the Unwanteds were actually taken to Artime, a magical land where the arts and creativity is a gift... and a weapon.
