There are four books in the Kidsboro series by Marshall Younger.
Battle for Control
The Rise and Fall of the Kidsborian Empire
The Creek War
The Risky Reunion
All four are in the church library under FIC YOU.
Younger is a writer for the Adventures in Odyssey radio program and there is some overlap between these books and AiO. These novels deal with a town created by a group of teenagers in the woods near Whit’s End. Ryan Cummings is the mayor of Kidsboro and is often called upon to fix the problems caused by less caring members of society.
Although the stories are fairly simple they do deal with some of the major issues facing any town such as good government, employment, and crime. The most poignant lesson presented to children reading these books is that if they are not actively involved in their society the lowest common denominator will reign.
