Is this a good story plot?

It is about a school full of people kidnapped because they have a supernatural ability they don't know about, well most don't. The main people are called Tessa Clarke, Artemis Gun and Aaron Smoke. Tessa was a 17 year old supermodel/actress/dance/singer with the perfect life. Artemis was the daughter of an army general and she was trained like a soldier from before she could walk, and things she shouldn't know. Aaron Smoke was the poorest of the poor, but his drawings have always been his closest friends. These 3 are the only ones who know what is going on at the school, more like a prison.
