Resumen
There was a terrible mistake. Wayside School was supposed to have been built with thirty classrooms all next to each other in a row. Instead, it was built with the thirty classrooms all on top of each other - thirty stories high! That may be why all kinds of strange stuff happens at Wayside School. Especially, on the thirteenth floor. It is a school full of unusual characters too. Mrs Gorf the meanest teacher in the world. Terrible Todd who always gets sent home early. John who can only read upside down. It is a crazy mixed up school brilliantly brought to life by the irresistible Louis Sachar.
