The Triplet Collectivemature

"First person narrative mode, changing narrators with each new chapter. Set in a North American high school setting. Three clairsentiently psychic siblings confront, for the first time in their lives, someone as odd and inexplicable as they were. He's an eccentric new student, being manipulated by a mysterious and shady organization. He doesn't play nice, however, it seems he's just a mere scout sent to assess whether the triplets are a threat. Eventually, someone winds up dead and the school goes into lock-down."
