This is part of a series by Melissa Perry Moraja about Madison and her siblings. In this book, Madison learns that being popular is not all it's cracked up to be. She is flattered and excited when the most popular girl in school, Sophia, pays attention to her. Sophia is only doing this because Madison is stage manager for the school talent show, but Madison doesn't realize that. Even with the guidance of her guardian angel, GA, she doesn't realize how poorly she is treating her friends in her rise to the status of "Little Miss Popular."
Younger chapter book readers who enjoy school and family stories like Junie B. Jones or the more journal-entry type books like the Dear Dumb Diary series would probably find this to their liking.
I read an e-book provided by the publisher through NetGalley.
There is a website for the series, as well as a Facebook page. If you especially like Madison and GA, they have their own website.
