The Rise and Fall of the Kidsborian Empire — Marshal Younger

Kidsboro is a small town in the woods behind Whit's End in Odyssey. It has a church, a store, a police station, a bakery, a newspaper, and a total of zero citizens over the age of 14. It's a town run by kids. Ryan, the mayor, helps enforce the laws, create new jobs, and keep the peace in a town where he seems to have lots of friends (and a few enemies).
Then, in The Rise and Fall of the Kidsborian Empire, years of Kidsboro prosperity come to a halt when one business owner selfishly sues another. Soon the kids-only town experiences a Great Depression.
