From the publisher:
It's the first day back at school for Arthur and Violet and all of their friends. Time for riding the school bus, going to class, and best of all, eating snacks and playing games at recess.
But this year the first day is full of surprises. The bus ride to school is an unexpected adventure, and Arthur's friend, Norman, almost loses his lunch box. Just when things settle down, Arthur finds his snack has disappeared from his lunch box. What will happen next on this exciting first day of school?
