Fifteen years ago, eight supernatural criminals fled Estero City to make a new life in an isolated tropical hideout. Over time, seven of them disappeared without a trace, presumed captured or killed. And now, the remaining one has died. Left behind to fend for themselves are the criminals’ five children, each with superpowers of their own: Birdie can communicate with animals. Brix has athletic abilities and can heal quickly. Tenner can swim like a fish and can see in the dark and hear from a distance. Seven’s skin camouflages to match whatever is around him.

Identical twins Fifer and Thisbe Stowe have amazing yet uncontrollable magical abilities. They're naturally more gifted than even their brother, Alex, the head mage of Artimé, could hope to be. But when they accidentally use their magic in the jungle of Artimé to strike down a beloved creature, Alex is furious and threatens to lock them away until they can learn to control their power.

When Alex finds out he is Unwanted, he expects to die. That is the way of the people of Quill: Each year all the 13-year-olds are labeled as Wanted, Necessary, or Unwanted. Wanteds get more schooling and train to join the army. Necessaries keep the farms running. Unwanteds are set for elimination. It’s hard for Alex to leave behind his twin, Aaron, a Wanted, but he makes peace with his fate - until he discovers that instead of a “death farm”, what awaits him is a magical place called Artime.

They have always scared him in the past - the Rangers, with their dark cloaks and shadowy ways. The villagers believe the Rangers practice magic that makes them invisible to ordinary people. And now 15-year-old Will, always small for his age, has been chosen as a Ranger's apprentice. What he doesn't yet realize is that the Rangers are the protectors of the kingdom. Highly trained in the skills of battle and surveillance, they fight the battles before the battles reach the people. And as Will is about to learn, there is a large battle brewing.
