A Wrinkle in Time – by Madeleine L Engle
No independent thought, creativity, or freedom is allowed in Camazotz. Everything is the same, from all kids bouncing their balls in uniform rhythms to adults living in tract homes and getting their milk in the morning all at the same time, the same way. Life is a pre-cut one-size-fits-all experience for all inhabitants of that planet and there is no getting free.
