Stilly River Sage, have you read the 'children's' book, "A Coyote Columbus Story," by Thomas King? Great illustrations by W. K. Monkman. Published in Canada by Groundwood (Douglas & McIntyre) in 1992.
Supposedly for grades 4-8.

Excerpt:
"Say, says Christopher Columbus. I'll bet this is India. And he looks at the human beings. I'll bet these are Indians. And he looks at his friends. I'll bet we can sell these Indians."
Just a little bit subversive.
