Welcome to Wayside School, where nothing is normal. Not only did the builder accidentally put each classroom on top of the other, but the students of the 30th floor have a problem: their teacher, Mrs. Gorf, can turn children into apples! Take a zany journey through the stairways of Wayside School as the students of the 30th floor try their best to navigate the temptation of pigtails, the non-existent 19th floor, a wayward cow and zillions of other challenges – including accepting one another for who they are.
