The Giant Yo-Yo Mystery: The Boxcar Children Mysteries, Book 107

Didn't know that people did such things but did know the names of some of the tricks mentioned. Interesting that practice , practice, practice was the theme for Benny. Today's youth think that everything comes on the first try. If you are a Yo-Yo person, this is a cute book.

These is a great mystery series. My 9 year old loved them but could read them in about a day.
