The veil of shadows. Book one of the shadowbound chronicles

All his life Lucas Sinclair had been normal. That's what he wanted to be. But since he had suddenly destroyed a school in less then a minute, he realized that he wasn't. Having been sent to a island that was secluded from everywhere else, he has to go to a school for people with magical abilities. Here they learn to control them, and use them in the real world. However he notices how certain things aren't the way they seem. With each day the school that had one seemed bright and sunny now getting darker. Now it's up to him and his new friends to figure out what's wrong.
