Aniwee: or, the Warrior Queen by Florence Dixie (1855 - 1905)

"I am going to tell you about a splendid unexplored country, and several adventures that happened therein, and I hope some day that some of you will go and see those countries, and penetrate even further into their mysteries, than did the girls and boys who figure in this book."

This is the original children's tale and should not be confused with the R rated 1987 movie of the same name. - Summary from the introduction
