Percy means to live and die by "The Code of the Bratchers"
Kentucky Chrome
Chapter One (in .pdf)
While the U.S. invades Iraq in 2003, Jack drives his motorhome into a state park in Kansas and embarks on a summer as a workamper. In the park's intricately hierarchical society, ex-con Percy Bratcher reigns supreme and enforces the rules, even as he lives according to a Code of his own.
When a little boy goes missing, Percy hunts down Jack.
