“We’re lethal, dangerous and most importantly, we belong the Academy. We’re their property.” I'm Gabby Brookes, I'm sixteen years old and training to kill. So I wouldn't get on my bad side if I were you. I live at Saint Hadwin’s Academy, a school for – if you be it – Super Heroes. Spies. Agents. Whatever you want to call it. We’ve trained our whole lives to protect the good from the bad. But there’s something special about us kids (aside from the fact we know how to kill a person in more than thirty different ways) each one of us has the ability we call a Major. A major is the element we can control: Fire, water, earth and air. I control air. Anyway, we don't do all this stuff for nothing, we get sent on missions, some low key and fine, but some highly dangerous. Yeah, you can guess which one I'm about to go on ... Let's just say the previous agent went missing and now It's my turn.

Nikki Star was an orphan, taken from foster home to foster home, when on her 15th birthday, she realized that she had the power to control fire. She's taken to a different school- for superheros- where she is trained to control her powers. Soon after she gets there, they need her help to stop an evil mastermind... and save the world.
