Louis Sachar writes great books for Tweens and middle-graders.  His award winning HOLES is a school and homeschool standard.  And he earned a  Newbery Medal for his contribution to American children's literature.

bookcovers of the 1st three Louis Sachar books in the WAYSIDE SCHOOL series

Each book in the Wayside series contains 30 chapters, with each chapter telling a story about the odd school that was build 30 stories high, with only one room per story.  (And no 19th story!)  If that isn't original enough, Mr. Sachar embues the tales with wonderful absurdity and magical realism that grips kids attention so that they demand more!
