I am a fan of this series, but I find this book lacking in comparison to the others. The story is similar in scope, the kids have a problem to solve, and they must use a STEAM concept to solve it. In this case it’s art. The kids are trying to sell cookies, but have no customers. Their art teacher sends them to stores to figure out why and then the kids get to work decorating and creating to get more sales. I guess the reason why this story bugs me is that, it takes more than art for sales. This story really covers marketing, but not the sales pitch portion. I think a different story line to cover art should have been used.
