Elementalists

Soren Legreve has not had a "normal life" but it was normal enough until he found his guardian and Uncle Burnt to death in the woods near his home. Now he has no home, and nowhere to go, and an organization known as Mantis is after him for his unique abilities. Then he is thrown into a world where kids have crazy powers and locked in a battle between those who ran away, and those who chose to stay.
