The giant yo-yo mystery Book

Henry, 14, Jesse, 12, Violet, 8, and Benny, 6, once ran away after their parents' deaths and chose to live in a boxcar rather than face the unknown with their Grandfather. Much time has passed and they are happily living with him. The boxcar has been moved to his yard.

In this 107th book, the children visit one of their grandfather's friends who is a woodworker and more skilled with a yo-yo than the grandfather. Benny has a yo-yo and wants to learn tricks. Jeff Naylor can do more than teach tricks-- he is attempting to gain a place in the McGinness Book of Records by building the world's biggest working yo-yo, but soon after the children begin helping him there is sabotage. Will Jeff be able to complete the task?

As always, The Bocar Children books deliver good moral values and a sense of strong family ties, fair play, hard work paying off, honesty, friendship, teamwork, resourcefulness, and much more.

This is a wonderful, almost timeless series for elementary aged children. Even though the author died in 1979, her books are enjoyed by young people even today. My children read them, and now my grandchildren are reading them. They love the adventures and mysteries found in each book.

I highly recommend reading the first book first, just to get the history. It really is not white necessary to read them in order, but it doesn't hurt.
