Chief [PDF ebook] 
Mistahimaskwa

On her way to school one day, Sarah is relieved to find the book she’d dropped the day beforeshortly after an encounter with a bear. But when she opens it, the story within, about the Cree chief Mistahimaskwa, comes alive. It takes Sarah back to the Saskatchewan Plains of 1832, where the young boy who would become the great chief first learns the ways of his people, to the final days of his life.
