The Formidable Five

Violet has never really fit in. With the ability to turn invisible and make things disappear and reappear at will, she counts herself as a weirdo and isolates herself from any possible relationships. When she moves to a new boarding school for her senior year, she discovers something shocking; four girls who are like her. However, they hold onto a dark secret, and soon Violet is in too far with them. Can she escape their clique before it's too late, or will she allow herself to become one of them, a killer?
