My rating: 5 of 5 stars
My five year old read it in two weeks, it was a fun light read.
While it is a soft sci-fi with many fantastical things happening,
it does include some real science as an entertaining introduction.
For me it checks off all the boxes, it has robots, is educational,
is good for my child’s reading development, and is entertaining.
So I give it 5 stars, well done Jon Scieszka!
