This book by Nancy Van Pelt is a very good and useful resource for children of ages between 10-12. It is a very good tool for understanding and ministering to their needs as they are in the "tween" age between being children and teenagegers.
Children in thsi age category are sometimes lacking in their needs especially in the children department of the church. Even at home, they are sometimes left out as concentration goes on the younger ones (ages 0-9) and the teens (ages13-19).
I therefore recommend this book to parents, bible workers, children leaders and Sunday or Sabbath School Cordinators as well as educators in the children department. It is a must read for all parents.
