Book Review: The Unwanteds

In the book Unwanteds by Lisa McMann, there is a dystopian city known as Quill, situated on an island. Every day on the Purge, the creative Unwanteds are sentenced to death, while the "strong and intelligent" (according to Quill) are sent to be trained. This year, Alex and Aaron Stowe are separated at the Purge, with Alex being sentenced to death, and Aaron going to the university. When he is eliminated, Alex discovers the magical land of Artimé, run by the enigmatic Mr. Today. In Artimé, the Unwanteds can harness their creativity to do magic, animate statues, and summon cheeseburgers. (Okay, not that last one.) However, Alex is missing Aaron because of their special twin bond. Would he do anything, including a permanent elimination to get Aaron back?
