This is the astonishing tale of June and Jennifer Gibbons, identical twins whose silent, antisocial exterior hid a rich, vast, creative life. From early childhood through their twenties, they spoke only to each other in a secret langauge, building an elaborate fantasy life. Then, from their self-imposed isolation, they were catapulted into the hormonal havoc of adolescence, plunging into a wild spree that led to their incarceration in a hospital for the criminally insane. A profoundly powerful and moving story.
