Although she is shy and quiet, Kitty likes going to school--and this is all due to her teacher, Miss Seabrooke. One day, Kitty's routine is thrown into disarray by a substitute teacher named Mr. Omar, who is nothing like what Kitty's used to. Kitty knows that Miss Seabrooke is counting on her to be helpful, so she sets about helping Mr. Omar and the other kids with the daily chores and lessons. They get through their day very happily together, and Kitty realizes that sometimes change is good and maybe even fun!
