Psycho Busters — Yuya Aoki

The action-packed fantasy novel that inspired the popular manga series!

With his family off in Hawaii for a week, fourteen-year-old Kakeru is looking forward to a little peace and quiet -- until he discovers a strange, beautiful girl in his room. Her name is Ayano, and she's in big trouble. Gifted with extraordinary psychic powers, Ayano is on the run from a shadow organization that wants to exploit her talents for its own dark ends. 

But how can a short, skinny, hopelessly ordinary junior high school student help Ayano and her equally talented friends? With a gang of ruthless henchmen and dangerous psychics closing in fast, Kakeru is about to discover a few surprises about himself: Maybe he's not so ordinary after all; perhaps he's even the hero of his own dreams. He can only hope, since the biggest, baddest psychic-hunter of all is coming after him for a life-or-death showdown.
