I read The Mystery of the Star Ruby for a project at Waukazoo Elementary. I thought it was a good book because it is a boxcar mystery and the kids are detectives that solve mysteries and they are in the same family. I think others would read it that are ages 8-11. I would recommend this book to kids from elementary school.
