Blurb from the book:
“Boys, let us get up a club.” With those words, six restless young men raided the linens at a friend’s mansion, pulled pillowcases over their heads, hopped on horses and cavorted through the streets of Pulaski, Tennessee. Soon, the six friends had named their club the Ku Klux Klan and all too quickly, their club would grow into the self-proclaimed Invisible Empire with secret dens spread across the South. The author of the Newbery Honor book Hitler Youth uses personal accounts unearthed from oral histories, congressional documents and diaries.

Seconded. I thought this was great non-fiction for adults and teens alike.
