I was very happy to learn there was another book with the Crimson Five, since I enjoyed Spin the Golden Light Bulb so much.

Kia and the rest of the Crimson Five are of to the Piedmont Challenge Global Championships, where if they place well their invention will be developed, making the stakes even higher. Then they learn they have even more to do than they initially thought. It's good they have new tasks, because that is where the team and the narrative excel at being inventive (pun intended).

I love the group's dynamics, as the importance and power of friendship is emphasized again. Patience is a virtue and must be practiced, even if you don't understand someone else's point of view. And let us not forget teamwork.

Not sure how I feel about the return of the principal. His meddling at the beginning is just distracting. Only later does it make sense.

Sweet, charming, the author's creativity soaring again with the plethora of all the gadgets, humorous names & activities etc, gifting you with childlike enthusiasm. This book is not only extremely entertaining, but also inspiring.

I liked the subtlety of the messages behind "Flip the Silver Switch" and how The Crimson Five brought out the best in each other through teamwork to compete in the Piedmont Global Championships. Great read for Middle Grade and Young Adult readers!
