In a distant future, a little girl named Anny makes toy mice out of scraps and dust. Anny has never seen a real mouse, just as she’s never seen the planet her family came from many generations ago. All she knows is her home, Tsedt: an isolated village of human colonists’ descendants and their friendly helper robots. But then one day the Amau arrive in Tsedt: plastic people with luminous eyes, intent on taking young humans to the distant city of Harbor to be educated. It’s not long before Anny is flown away to a place unlike any she’s seen before.
