Derwood Inc. (Peabody Adventure Series #1)

When Penny Derwood and her seventh-grade class tour a button factory, she accidentally gets involved in a mystery that she and her brother, Jack, are determined to unravel. In their efforts to solve the mystery, they undergo a series of hilarious adventures and at the same time begin to learn something about teamwork, family unity, and accepting one another.

The Peabody Series, named for the imaginary town of Peabody, Wisconsin, centers on a group of Christian young people who attend the same local church. Each book focuses on a new adventure that involves several members of the youth group. The characters in these books do not find quick solutions to their difficulties. Like all Christians, they struggle to grow, sometimes losing ground, but ultimately coming to a deeper knowledge of the Lord.
