When the contest is about to start, pop star Madlynn Rose disappears and soon after they discover that she is gone. One of the judges tells the Boxcar Children about the disappearance.

“I thought I could outrun you since it’s my job to be fast and strong. I guess I couldn’t. Or I couldn’t outrun that slippery puddle.”

The Boxcar Children: The Mystery of the Missing Pop Idol created by Gertrude Warner is another in the series of modern Boxcar Children mysteries. This book was not written by Warner, but the real author is not disclosed. The four children are curious and want to solve mysteries. Each of the children has their own personality and strengths and weaknesses. The book is written in an easy to read and follow fashion. The mystery makes sense and does not jump through hoops to come to its conclusion. Although this is Boxcar Children Mystery number 138, it is not necessary to read all of the previous books to understand this one or to get into the characters.

This book is good for young readers of mysteries, ages 8 to 14. It is clean and although some people are mean in the story that just adds some realism to the story. Whether you’re a long-time fan or a novice to this series, this is a good book.
