Oh No! Not Again!: (or How I Built a Time Machine to Save History) (or at Least My History Grade) by Mac Barnett

2.0

This book was simply too silly for me, and the ending is illogical and too open for my liking. And what is the 'message' of this book? "Children shouldn't time-travel even if they are geniuses who can"?
