Kisimoto Sasukan was only five when he lost his father in a tragic water-car accident. Alone and shaken, he was taken in by a reporter for an interview-until his desperate mother and sister arrived, searching for him, hearts heavy with worry. Years passed, but fate had more in store. At twenty-three, Kisimoto and his family were taken by a shadowy NGO-held captive under the threat of execution. But the threats were a mere illusion; the experiments were real. He wasn't alone-forty others, scattered across the globe, suffered the same fate. Their bodies became test subjects. Their lives became data. Until one day, Kisimoto did the impossible. He escaped, dragging his mother and sister to freedom. But the scars of experimentation ran deeper than he imagined. As the hunt for the missing subjects raged on, Kisimoto discovered something new. Something terrifying... He wasn't the same anymore... And he was done being their pawn. Read on to uncover the truth.
