Twister on Tuesday by Mary Pope Osborne-71 pages

As with most of the Magic Tree House books thus far, I read a newer edition. In this story, Jack and Annie are taken back to pioneer-era Kansas. There they find a one-room schoolhouse where they find something to learn, which is the third type of writing needed for Morgan Le Fay to save Camelot. Jack and Annie also learn a valuable lesson about perseverance.
