The writing was well done. I didn't see any flaws. The story was a bit ho-hum, but I get that it's meant for young children.
I also get that the writer was trying to add a bit of actual schooling into a rather overall dull tale, but went a bit overboard with the bubble amusement park. No, if children in bubble suits started banging into one another, they wouldn't start soaring through the sky with the greatest of ease; they'd fall over and have a difficult time getting up.
Overall, I get what the writer is trying to do -- write a tale about COVID for the next generation. Exaggerated, so our current distance learning won't seem so bad. The best part of the book was the art work, which was very good.
