There have been a terrible mistake. Wayside School was supposed to be built with 30 classrooms all next to each other in a row. Instead, they built the classrooms one on top of the other 30 stories tall. The Builder said he was very sorry. That may be why all kinds of funny things happen at Wayside school... especially on the 13th floor. You'll meet Mrs garth, the early, and John he couldn't read only upside down, along with all the other crazy kids in this mixed up school that came out sideways. But you'll never guess the truth about sammy, the new kid and what's in store for Wayside School on Halloween
