A very nice little book.
It is about a kid, who is frustrated with his mistakes. He gets so fed up that he wishes mistakes disappear from reality. He falls asleep and dreams of a world with no mistakes. He is surprised to see that a world with no mistakes is also a world with no evolution, no progress, and no learning. He wakes up, very received to normal reality.
This story is well thought, fun and engaging. The message is good and clear, comes through in an interesting way.
The illustrations are appealing. A mix of manga with soft, nice watercolors style. I would recommend this book for all young girls and boys.
