I was excited to get into this book, but upon reading the first quarter, I realised that it's a bit too kid-like for me. I enjoyed the idea of a story that is both about people and science/technology, though. The kids have impressive interests for their age, and even though George is the only one mentioned in the title, I felt that Annie deserves equally as much credit as she seems to play a key role.

I liked the additional information scattered through the book, but I felt that it fragments the storyline it's rather difficult to be understood by the target age group. The artwork was also very cute and fitting.
